ELECTROPHOTOGRAPHIC PHOTORECEPTOR SUBSTRATE, ITS MANUFACTURING METHOD, ELECTROPHOTOGRAPHIC PHOTORECEPTOR USING THE SUBSTRATE, AS WELL AS ELECTROPHTOGRAPHIC PHOTORECEPTOR CARTRIDGE USING THE PHOTORECEPTOR AND IMAGE FORMING APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide an electrophotographic photoreceptor substrate easily manufacturable with high productivity, without causing image defects. SOLUTION: In this electrophotographic photoreceptor substrate 1 with fine grooves formed on the surface, the shape of the grooves is curved when the surface of the substrate is developed on a plane, and intermittent. The electrophotographic photoreceptor can be put into practical use in an optional field requiring it, and is suitable to, for example, a copying machine, a printer or a printing machine.
