ELECTROPHOTOGRAPHIC PHOTORECEPTOR, IMAGE FORMING METHOD USING ELECTROPHOTOGRAPHIC PHOTORECEPTOR, IMAGE FORMING APPARATUS, AND PROCESS CARTRIDGE FOR IMAGE FORMING APPARATUS

摘要

A photoreceptor includes a conductive support body, an intermediate layer, and a photosensitive layer. The intermediate layer is made of gallium nitride (GaN) crystals having electron affinity greater than that of the photosensitive layer and formed between and in contact with the conductive support body and the photosensitive layer. The photosensitive layer is composed of either a single layer type photosensitive layer or a laminated type photosensitive layer.
