ELECTROPHOTOGRAPHIC PHOTOSENSITIVE BODY, METHOD FOR PRODUCING CONDUCTIVE BASE, IMAGE FORMING DEVICE, AND ELECTROPHOTOGRAPHIC CARTRIDGE

摘要

An electrophotographic photoreceptor having high performance that hardly generates image defects such as black spots, color spots, and interference fringes is provided. The electrophotographic photoreceptor includes an undercoat layer containing metal oxide particles and a binder resin on an electroconductive substrate having a maximum height surface roughness Rz in the range of 0.8 ‰¤ Rz ‰¤ 2 µm, and a photosensitive layer disposed on the undercoat layer, wherein the metal oxide particles have a volume average particle diameter of 0.1 µm or less and a 90% cumulative particle diameter of 0.3 µm or less which are measured by a dynamic light-scattering method in a liquid containing the undercoat layer dispersed in a solvent mixture of methanol and 1-propanol at a weight ratio of 7:3.
