Abstract

PURPOSE:To obtain a color copy image by using a photoreceptor smaller than the area that corresponds to picture area, by sticking a developer to an image receiving member while moving the photoreceptor in an electric field of a potential image formed by a difference in distributed voltage due to fluctuations of the resistance of a photoconductive layer. CONSTITUTION:On color filter 1, a strip of opaque electrode 4 of Cr, etc., is vapor- deposited to a width of 25mum and about 50mum away from it, a strip of transparent electrode 3 of InO, etc., is formed to a width of 25mum. Next, photoconductive layer 5 of amorphous silicon covering electrodes 3 and 4 is formed and isolated conductors 6 of 200 by 200mum are provided on it at intervals of 100mum by vapor-deposition Au, etc. Photoreceptors 7, 8 and 9 provided with red, green and blue filters 10, 11 and 12 at the opposite side to transparent supporter 2 are moved on image receiving member 19 as shown by the arrow. The image of original 17 is exposed and photoreceptors 7, 8 and 9 are applied with voltages to stick a developer to member 19 via photoconductive layer 5 by an electric field generated by conductor 6. Thus, a clear color picture appears on member 19.
