ELECTROPHOTOGRAPHIC PHOTORECEPTOR AND IMAGE FORMING APPARATUS

摘要

An organic photoreceptor comprising a cylindrical support having thereon at least a charge generation layer and a charge transport layer, the cylindrical support having a corrugation processing profile along a central axis direction of the cylindrical support provided on a circumferential surface of the cylindrical support, wherein the corrugation processing profile meets Formula 1: 10 μm≦̸&Dgr;L,  Formula 1 provided that &Dgr;L represents a maximum value of variation of periods of the corrugation processing profile within an image-forming region of the cylindrical support, and the charge generation layer comprises a gallium phthalocyanine pigment.
