PURPOSE:To increase the electrostatic charge potential of the photosensitive body so as to eliminate the interference fringes by coherent light and to uniformize blackening by subjecting the anodized Al film on the surface of an Al substrate to electrolytic coloration then using said film. CONSTITUTION:The title photosensitive body is produced by forming the ano dized Al film 2 subjected to the electrolytic coloration on the Al substrate 1, then laminating a charge generating layer 3 and a charge transfer layer 4 successively on the film 2. The film 2 is formed by forming the anodized Al film on the Al substrate to 3-20mum film thickness, then subjecting the film to the secondary electrolytic coloration treatment and sealing treatment. The layer 3 is formed by coating the coating liquid contg. a charge generating material (e.g. squarylium pigment) and a binder resin (e.g. butyral resin) on the above-mentioned film and the layer 4 by coating the coating liquid contg. a charge transfer material (e.g. arom. tertiary diamino compd.) and a binder resin (e.g. polycarbonate) on said layer, respectively. |
