发明名称 FOUR-COLOR ELECTROPHOTOGRAPHY
摘要 PURPOSE:To obtain a good image free from image disturbance by using a specified composite photosensitive body composed of a conductive substrate and 2 photoconductive layers formed on the substrate. CONSTITUTION:The cylindrical composite photosensitive body 10 is formed by laminating the 2 photoconductive layers L, U on the conductive substrate BS, and it is adjusted so that when the body 10 is exposed to colors A and B, one of the photoconductive layers L, U is made electrically conductive, and when exposed to a color C, the other of L, U is made conductive, where A, B are optional 2 colors of red, blue, and green, and C is the color of the rest. When 4 processes of red, blue, green, and black light exposures are executed, independent of each other, an electrostatic latent image of each color image can be separated from each other, thus permitting the high-quality 4 color image free from image disturbance to be obtained by developing these electrostatic latent images and transferring the developed images on the same transfer paper.
