<p>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.
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 Ra 1 and Ra 2 independently 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 R 1 and R 2 independently represents one selected from the group consisting of a hydrogen atom, an alkyl group, an aryl group, a halogen group, and an alkoxy group.</p> |
