ELECTROPHOTOGRAPHIC PHOTORECEPTOR, METHOD FOR PRODUCING ELECTRIC CHARGE GENERATING PIGMENT, IMAGE FORMING DEVICE, AND PROCESS CARTRIDGE

摘要

PROBLEM TO BE SOLVED: To provide a highly durable electrophotographic photoreceptor not causing image defects such as black spots and image faults such as fog and the lowering of image density and excellent in environmental stability and to provide a method for producing an electric charge generating pigment, an image forming device and a process cartridge. SOLUTION: In the electrophotographic photoreceptor having an electric charge generating layer and an electric charge transferring layer on an electrically conductive substrate, the thickness of the electric charge transferring layer is 22-35μm and an electric charge generating pigment contained in the electric charge generating layer contains 150-9,000 ppm sulfur component.
