Abstract

PURPOSE:To render the state of a photoreceptor constant before and after copying, by effecting charging and uniform light illumination in a step immediately before the copying step using a 2-layer structure photoreceptor, whose photoconductive layer is formed of CdS. CONSTITUTION:Charging unit 2, an exposing unit for illuminating photoreceptor 1 from illuminating unit 4 through slit 3, and developing unit 7 are arranged around 2-layer structure photoreceptor 1 made by forming a photoconductive layer of CdS on a conductive substrate. Photoreceptor 1 is charged with unit 2 and illuminated by uniform light with the exposing unit before undergoing a copying process by unit 2, the exposing unit, and unit 7. Then, an electrostatic latent image formed by the copying process on the photoreceptor 1 surface is visualized, thus permitting a copied image with small density variation to be obtained because of the state of photoreceptor 1 made constant before and after copying.
