ABSTRACT:
Disclosed is an electrophotographic photoreceptor which is excellent in wear resistance and electrical characteristics. Specifically disclosed is an electrophotographic photoreceptor containing a polyester resin in a photosensitive layer provided on an electroconductive substrate. The polyester resin is composed of a copolymer represented by the general formula 1 below, which has a viscosity average molecular weight (Mv) of 10,000-300,000 and contains a diphenyl ether 4,4′-dicarboxylic acid component and a bivalent phenol component.[Chemical Formula 1]in-line-formulae description="In-line Formulae" end="lead"?A-Bn  (1)in-line-formulae description="In-line Formulae" end="tail"?In the general formula 1, A represents a diphenyl ether 4,4′-dicarboxylic acid residue represented by the formula A below, and B represents a bivalent phenol residue represented by the formula B below.In the formula A, each of Ra1and Ra2independently represents a hydrogen atom or a monovalent substituent which may have a substituent, and each of n and m is independently an integer from 0 to 4. In the formula B, each of R1and R2independently represents one selected from the group consisting of a hydrogen atom, an alkyl group, an aryl group, a halogen group, and an alkoxy group.
