ELECTROPHOTOGRAPHIC PHOTORECEPTOR, PROCESS CARTRIDGE, AND ELECTROPHOTOGRAPHIC APPARATUS

摘要

Disclosed is an electrophotographic photoreceptor that can continually exhibit the effect of relaxing stress of contact with a contact member or the like and, at the same time, has an excellent potential stability during repeated use.  Also disclosed are a process cartridge comprising the electrophotographic photoreceptor, and an electrophotographic apparatus.  The electrophotographic photoreceptor comprises a charge transport layer as a surface layer.  The charge transport layer comprises a charge transport material and at least one resin of a polyester resin A comprising a siloxane site, a polyester resin C, and a polycarbonate resin D.  The content of the siloxane site in the polyester resin A is 10 to 40% by mass based on the total mass of the polyester resin A.  The charge transport layer has a matrix-domain structure that comprises a matrix and a domain formed of the polyester resin A provided in the matrix.  The matrix is formed of the charge transport material and at least one resin of the polyester resin C and the polycarbonate resin D.
