摘要： PURPOSE:To obtain images with high sensitivity and good at contrast and gradation characteristic by providing means for irradiating a photoconductor with information light, means for uniformly heating and photoconductor, means for totally exposing the photoconductor, and an auxiliary means for uniformly exposing the photoconductor using one part of light of the total exposure. CONSTITUTION:The feed of a photoconductor 1 is started is response to a record starting signal and information is written on the photoconductor 1 through exposure. After writing is finished, the feed of the photoconductor 1 is stopped and the photoconductor 1 is cut 34. The photoconductor 1 is allowed to pass through a reinforcing exposure portion 2, a heating developing portion 23 and a total exposure portion 24. After the photoconductor 1 is detected by a passage sensor an image pickup body 9 is allowed out of an image pickup body cartridge 49. Next, the photoconductor, the image pickup body, a feed motor and a drive motor are stopped and the image pickup body 9 is cut. Then a driving motor for a feed roller is turned on and the photoconductor 1 and the image pickup body 9 are passed through transfer rollers 52, 53 and images are transferred thereon while the photoconductor 1 and the image pickup body 9 are made to lie on upon the other. Each time an image is transferred, the photoconductor 1 and the image pickup body 9 are separated from each other and discharged 60, 61. Images with high sensitivity and good at contrast and gradation characteristic are thus obtained.

摘要： PURPOSE:To obtain the planographic printing which can be formed by dry processing by polymerizing layers contg. a polymerizable compd. and a polymn. initiator in the form of images to form a polymerized part surface and unpolymerized part surface and sticking powder only to the surface of the unpolymerized part by utilizing the difference in the tacky adhesiveness between the two surfaces. CONSTITUTION:The latent images consisting of the polymerized parts 2-a and the unpolymerized parts 2-b are formed according to the patterns of a mask 4 when an original plate 5 for planographic printing constituted by forming the polymerized layer 2 contg. the polymerizable compd. and polymn. initiator on a base 1 is exposed via the mask 4. An oxygen barrier layer 3 of the original plate for planographic printing formed with the polymerized latent images is peeled and the powder 6 is sprayed, by which the powder is stuck onto only the unpolymerized parts having the tacky adhesiveness. The original plate is then subjected to full-surface exposing by the same light source and the powder 7 stuck to the unpolymerized parts is fixed by the polymn. of the polymerizable compd. The planographic printing plate is obtd. if the excess powder is thereafter removed.

摘要： PURPOSE:To efficiently form polymerized images in a short period of time and to obtain color images having decreased color fogging by having an intermediate layer consisting of a layer formable high-polymer material between a color material layer and a polymerized layer. CONSTITUTION:The layers of the image forming medium are constituted of a base 5, the color material layer 4, the intermediate layer 3, and the polymerized layer 2. The intermediate layer is formed of the high-polymer material capable of forming laminar films by dissolving this material in a solvent and applying the soln. on a base material, then evaporating away the solvent or extrusion coating the soln. by melting onto the base material. The intrusion of a thermally diffusive material from the color material layer to the polymerized layer, etc., is then prevented by this intermediate layer at the time of a coating state of respective layers at the time of production of the medium consisting of, for example, nitrocellulose, etc., and a heating stage at the time of full-surface exposing. The generation of the adverse influence by the light absorption of the thermally diffusive material, such as desensitization of the polymerizable compd. and decrease in curing rate, is obviated. The polymerized images are thus efficiently formed in the extremely short period of time and the color images having the extremely decreased color fogging are obtd.

摘要： PURPOSE:To easily realize a large area, and also, to reduce the power consumption, and moreover, to obtain a display medium of abundant colors and its display method by forming plural image areas by at least two kinds of high polymer liquid crystals of different liquid crystal phase temperatures on a substrate provided with a heating layer. CONSTITUTION:By executing an electric conduction for two seconds by 30V voltage to a heating layer 5 through an electrode 6, a display medium is heated to 110 deg.C, and thereafter, by quenching it to a room temperature by using a fan 7, all high polymer liquid crystals are led to a transparent state. In this case, the display medium looks transparent. Also, by a thermocouple provided on the surface of a substrate, a temperature of the surface of the substrate can be known. Subsequently, by executing an electric conduction for one minute by 30V voltage to the heating layer 5 with respect to the display medium, it is heated to 110 deg.C, and thereafter, it is quenched by the fan 7 until it becomes 80 deg.C, and thereafter, by leaving it as it is until it becomes a room temperature, it is cooled slowly and only a high polymer liquid crystal can be set to a scattered state, and a white liquid crystal image can be recognized.

摘要： PURPOSE:To stably and simply print in large quantity by a recording peripheral device to be applied to a computer, etc., by utilizing change in adhesive properties of ink in response to polarity of an applied voltage. CONSTITUTION:Ink 2 of recording material is formed in a uniform thickness on an ink carrying roll 1 by a coating roll 9, ink 11 kneaded by kneading means 20 is supplied to the roll 9, and guided to an ink reservoir 10 upon rotation in a direction of an arrow E. A plate 4 wound on a plate roll 3 is brought into contact with the ink 2 on the roll 1, and the roll 3 is rotated reversely to the roll 1. A desired pattern 4b made of an insulating material is provided on a base material 4a made of a conductive material on the plate 4. A voltage is applied from a power source 103 between the plate 4 and the roll 1 to change the adhesive properties of the ink 2 in contact with the conductive part of the plate 4 to adhere the ink 2 on the pattern due to the difference of the adhesive properties, thereby forming an ink image. Thus, a large quantity printing can be stably performed for a long period.
