摘要： The object of the invention is to provide a highly characteristic and lesser defective image using an electrophotographic photoreceptor which can be produced with a better coating property and which is highly sensitive and hardly loses the electrostatic stability during repeated use. A water-soluble or water/alcohol-soluble polyvinyl acetal and an inorganic pigment are involved in an underlayer provided between a conductive support and a photoconductive layer. Particularly, it is favorable to use titanium oxide as the inorganic pigment, make the ratio of polyvinyl acetal/titanium oxide 1/9-9/1 by weight, make the underlayer 0.5-5 .mu.m in thickness, use the titanium oxide of which the surface is treated with alumina, use the titanium oxide of which the titanium oxide component is 95% by weight or lower and of which the surface is treated with alumina, use the polyvinyl acetal of which the sodium ion concentration is 40 ppm or lower, and use the photo-conductive layer which contains a vinyl chloride-vinyl acetate type copolymer. As for a dispersing medium for coating the underlayer, water/alcohol=1/9-7/3 (ratio by weight) is selected. The aforementioned photoreceptor is applied to an image-forming apparatus using an inversion development process.

摘要： An electrophotographic photoreceptor, in which the increase of VL is controlled below 15 V by controlling the content ratio M (ppm) of a charge transporting material CTM2 to a charge transporting material CTM1 within a specific range, wherein the ionization potential Ip(2) of the CTM2 is smaller than the ionization potential Ip(1) of the CTM1 in the constituent of the photosensitive layer, and thereby the electrophotographic photoreceptor has only a little reduction of image concentration. A method for producing an electrophotographic photoreceptor having ΔVL which is controlled below 15 V, wherein, in a case where the ionization potential of the charge transporting material used in the previous run of production is small, ΔVL can be set below 15 V by using, in the next production, a dip coating liquid, which comprises, as a constitutive material, a charge transporting material in which the difference between the ionization potential of the current material and that of the previous material is set below 0.25 eV.

摘要： A multiple number of image forming stations are provided for multiple development colors including black. Each station having a photoreceptor. Each one of the photoreceptors has a charge transport layer including a binder resin that is a blend of at least two kinds of resins. The blended ration of at least two kinds of binder resins for the photoreceptor for black is made different from that of the binder resins for the photoreceptors for the other development colors. The photoreceptor for black presents a greater abrasion resistance than the photoreceptors for the other development colors. This structure makes it possible to use all the photoreceptors for back and colors, for and within, a concurrent period.

摘要： The object of the invention is to prevent interference fringes of images and allow precise measurement of the thickness of a layer by the optical interferometry by limiting the surface roughness of a conductive substrate. The surface roughness of the conductive substrate provided in an electrophotographic photoreceptor is such that the maximum peak-to-valley roughness height (Ry)=0.8 to 1.4 μm, the centerline average roughness (Ra)=0.10 to 0.15 μm, the ten-point average roughness (Rz)=0.7 to 1.3 μm, the average peak-to-peak distance (Sm)=5 to 30 μm, and the peak count Pc=60 to 100. In such an electrophotographic photoreceptor, light for exposure can be scattered to an appropriate extent, so that interference fringes can be prevented, and an interference pattern is formed during measurement of the thickness of the photosensitive layer by the optical interferometry so that the thickness of the layer can be measured with a high precision.

摘要： An object of the invention is to provide a highly characteristic image using an electrophotographic photoreceptor of which a charge-generating layer can be produced with a better coating property and which is highly sensitive and electrostatically highly stable in repeated use. The charge-generating layer of a function-separated type photoreceptor contains a n-type non-metallic phthalocyanine and a copolymer of vinyl chloride-vinyl acetate type. Particularly, the ratio of the .tau.-type non-metallic phthalocyanine to the copolymer of vinyl chloride-vinyl acetate type is fixed at 1/3-3/1 by weight. The thickness of the charge-generating layer is fixed at 0.1-0.6 .mu.m. As the copolymer of vinyl chloride-vinyl acetate type, copolymers of vinyl chloride-vinyl acetate, vinyl chloride-vinyl acetate-maleic acid, or vinyl chloride-vinyl acetate-vinyl alcohol are selected. Particularly, it is favorable to select those containing at least 10% by weight of the vinyl alcohol component. The charge-generating layer is formed with a liquid coating material using a ketone solvent as dispersant. The aforementioned photoreceptor is applied to an image-forming apparatus using an inversion development process.
