ABSTRACT:
A photosensitive member for electrophotography basically comprises a conductive support, on the surface of which a photoconductive layer and a transparent insulating layer are sequentially laminated. The photosensitive member is adapted to be used in a process for forming an electrostatic latent image including sequential steps of a primary corona charging concurrent with imagewise exposure, a secondary corona charging and a flush irradiation. The surface of the conductive support is treated to a mirror finish, based on experimental finding that the contrast voltage of the latent image depends on the degree of surface roughness of the support.
