摘要： PURPOSE:To prevent generation of flow in a picture image, to improve the quality of the image, and to stabilize the characteristics of a photosensitive body by forming an intermediate layer comprising optional amorphous material layers wherein the surface of the amorphous material layers are smoothened. CONSTITUTION:A surface of an intermediate layer 37 is smoothened by polishing in a midway of film forming stage of plural amorphous material layers 36-38, and all film forming processes are completed thereafter. Thus, the surface roughness of a photosensitive body 34 is improved and the surface area of the photosensitive body 34 is reduced substantially. The absolute amt. of deposition of materials produced by Corona discharge is reduced, and removal of the deposited material produced by the Corona discharge is facilitated, so deterioration of surface resistance due to long time use is avoided. Moreover, exposure of free bonds formed by the polishing on the surface of the photosensitive body 34 is prevented because a surface protecting layer 38 contg. C atoms. and having high carrier transfer characteristic and high potential retaining effect is formed on the front polished photoconductive layer 37. Thus, the characteristics of the photosensitive body are improved, generation of flow in the picture image is prevented, and the quality of image is improved.

摘要： PURPOSE:To prevent generation of flow in a picture image and to improve the quality of the image by forming an intermediate layer comprising optional amorphous material layers wherein the surface is smoothened and free bonds formed by the smoothening are bonded to H atoms. or to other free bonds to each other. CONSTITUTION:The surface of an intermediate layer 37 is smoothened in the midway of forming films of plural amorphous material layers 36-38 by polishing, and all film forming processes are carried out thereafter. When free bonds laid bare on the surface of a photoconductive layer 37 during polishing are bonded to O atoms. in the air or to OH groups, generation of flow in the picture image would be caused. But the generation of flow in the picture image due to oxidation is prevented because the polishing is executed in vacuum and free bonds are bonded primarily to each other. Moreover, the chargeability of the photosensitive body 34 is improved since a surface protecting layer 38 contains C in order to enhance carrier transfer property and potential retaining effect. By this constitution, the characteristics of the photosensitive body are improved, generation of flow in the picture image is prevented, and the quality of the image is improved.

摘要： PURPOSE:To prevent an electrophotographic sensitive body from causing flow of image by constituting the electrophotographic sensitive body of an electroconductive substrate and an a-Si layer formed thereon, and giving a smooth polished surface having a specified surface roughness to the a-Si layer. CONSTITUTION:A charge injection inhibiting layer 2, a photoconductive layer 3, and a surface protecting layer 4 are formed successively on an elec troconductive substrate 1. Thus, an amorphous material layer (a-Si layer) contg. Si is formed on the substrate 1. Said a-Si layer has a smooth polished layer having 0.2mum Rmax, namely below 0.08mm L surface roughness. Accordingly, sites for adsorbing and depositing products of corona discharge are reduced, so the amt. of adsorption and deposition are reduced. At the same time, removal of the adsorbed material and deposited material by a mechanical means for removal such as cleaning blade method is facilitated. By this constitution, a photosensitive body is prevented from causing flow of image.

CONSTITUTION:The charged area 13 in the surface of the photosensitive body 1 is charged electrostatically by an electrostatic charger 3 while a drum 2 is rotated and an electrostatic image is formed on the surface of the photosensitive body 1 by image exposure 12; and toner 5 is supplied from a developing device 6 to the surface of the photosensitive body 1 to develop the electrostatic latent image, which is transferred to transfer paper 11 by a transfer charger 7.

摘要： PURPOSE:To extend the time required from destaticization to the next electrostatic charging and to suppress a drop in the electrostatic charging potential of a photosensitive body by destaticizing the photosensitive body by a destaticization means before cleaning the surface of the photosensitive body by a cleaning means. CONSTITUTION:An electrostatically charged area 13 on the surface of the photosensitive body is charged electrostatically by the electrostatic charger while a drum 2 is rotated, and then an electrostatic image is formed on the surface of the photosensitive body 1 by image exposure 12; and toner 5 is supplied from a developing device 6 to develop the electrostatic latent image, which is transferred to transfer paper 11 by a transfer charger 7. Then, the surface of the photosensitive body 1 is irradiated with light from a destaticizing lamp and then toner 5 remaining on the surface of the photosensitive body 1 is removed by a cleaning blade 8. In this case, the surface of the photosensitive body 1 is destaticized before cleaned. Consequently, the time required from the destaticization of the photosensitive body 1 to the charging is extended, the majority of carriers generated on the photosensitive body 1 by light irradiation are coupled up to the electrostatically charged area 13, and the possibility of a decrease in electrostatic charging potential in the next charging is reduced.

摘要： PURPOSE:To enable optional and dynamic variation of absorption wavelength region by forming a photosensitive layer contg. a binary amorphous material made of C and Ge on a conductive substrate, and changing these contents. CONSTITUTION:The binary amorphous material made of C and Ge without using Si can be dynamically changed in the absorption ends of the absorption wavelength region by changing the content ratio of C to Ge. Since the amorphous Ge carbide can be generally changed by 1-3.5eV as the optical forbidden band width, the whole wavelength region necessary for the photosensitive material from the near 1R rays to the near UV rays can be covered. When the photosensitive body 21 is formed in a CVD device 9, a conductive substrate 11 cleaned of grease with trichloroethylene is placed on a susceptor 13 in a reactor 10, electric discharge is caused in an atm. of argon fed from a gas feed system 17 to deposit a carrier injection barrier layer 22, and then, to form a carrier generating layer 23 and a carrier transfer layer 24, and finally a surface layer 25, in succession.

摘要： PURPOSE:To obtain an electrophotographic sensitive body which has substantial photosensitivity particularly to long wavelength light such as laser light and obviates the generation of interference fringes by providing coarse boundary faces in parallel or coaxially with the surface into the photoconductive layer on a conductive substrate. CONSTITUTION:For example, Se is first deposited by evaporation on the conductive substrate 11 and the boundary face 13 thereof is roughened by wet or dry process etching or mechanical treatment in the stage of forming the photoconductive layer on said substrate. The photoconductive layer consisting of an Se-Te alloy is then thinly laminated thereon so that the surface 14 of the laminated photoconductive layer 12 reflects the rough surface of the layer 13. The laminated photoconductive layer 22 of which the boundary face between the layers 22-01 and 22-2 is roughened and the surface 24 of the layer 22-2 is also roughened is otherwise formed in the stage of forming a carrier transfer layer 221 and carrier generating layer 22-2 in this order on the base 21 surface. The apparent decrease in the photosensitivity with the coherent light such as laser light in particular owing to the interference between the light incident to the photosensitive bodies 10, 20 and the light reflected from the layer boundary faces 13, 14, 23, 234 is prevented by forming the photoconductive layer in the above mentioned manner. The electrophotographic sensitive body having substantial photosensitivity is thus obtd.

The layers 2, 3 contain preferably H or halogen, and it is preferable that a small amount of B or P is incorporated to regulate the specific resistance of the layer 2 to OMEGAcm and that of the layer 3 to >=10 OMEGAcm. A protective layer 5 of a-Si contg. O, H, N or C is then formed on the layer 4. Thus, a sensitive body having high potential by electrostatic charge and no residual potential after exposure is obtd. This sensitive body has high resistance to bias for development and a long life.
