ELECTROPHOTOGRAPHIC PHOTORECEPTOR, METHOD OF IMAGE FORMATION, IMAGE FORMATION APPARATUS AND PROCESS CARTRIDGE FOR IMAGE FORMATION APPARATUS

摘要

An electrophotographic photoreceptor excelling in image stability and capable of realizing prolonged durability. There is provided an electrophotographic photoreceptor comprising a conductive support and, sequentially superimposed thereon, at least an undercoat layer, a photosensitive layer and a crosslinked charge transport layer, wherein the undercoat layer is composed of at least two layers of a layer containing an inorganic pigment and a layer containing no inorganic pigment and wherein the crosslinked charge transport layer is formed by hardening of at least a trifunctional or higher functionality radical polymerizable monomer without charge transport structure and a monofunctional radical polymerizable compound with charge transport structure.
