PROBLEM TO BE SOLVED: To provide an electrophotographic photosensitive body which is excellent in wear resistance and electrical characteristics. SOLUTION: The electrophotographic photosensitive body contains polyester resin which is a copolymer of a diphenylether-4,4'-dicarboxylic acid component and a divalent phenol component in a photosensitive layer arranged on a conductive base, wherein the copolymer is represented by general formula (1) and has a viscosity average molecular weight (Mv) of 10,000-300,000. The electrophotographic photosensitive body is excellent in wear resistance and electrical characteristics. In the formula (1), A is a diphenylether-4,4'-dicarboxylic acid residue of a specific structure; and B is a divalent phenol residue of a specific structure. COPYRIGHT: (C)2006,JPO&NCIPI
