ELECTROPHOTOGRAPHIC PHOTORECEPTOR, ELECTROPHOTOGRAPHIC PHOTORECEPTOR CARTRIDGE, AND IMAGE-FORMING DEVICE

摘要

The purpose of the present invention is to provide an electrophotographic photoreceptor in which adhesion of a photosensitive layer is very adequately maintained, and in which good electrical characteristics and image characteristics are both obtained, regardless of the magnitude of shrinkage. This present invention relates to an electrophotographic photoreceptor having at least an undercoating layer and a photosensitive layer on an electroconductive substrate, wherein the undercoating layer contains a binder resin, and the binder resin contains a polyamide resin having an elastic deformation ratio of 56.0% or more.
