[PROBLEMS] To provide a novel high-performance charge-transporting polyester which is easy to produce and an electrophotographic photoreceptor using the same. SOLUTION: At least one kind of a structure represented by the following general formula (I) as a dicarboxylic acid component, and at least one kind of a structure represented by the following general formula (II) as a diol component: Each is contained as a partial structure of a repeating unit, and has a weight average molecular weight of 10,000 to 300, 000 charge transporting polyesters. -CO- (T) a-A- (T) a-CO- (I) -O- (T) b-A '-(T) b-O- (II) wherein A and A' are And a divalent group represented by the following formula. Embedded image (R 1 , R 2 and R 3 are each independently a hydrogen atom, X represents a halogen atom, an alkyl group, an alkoxy group, or a substituted or unsubstituted aryl group, and X represents a substituted or unsubstituted divalent organic group. a, b, k and m each represent an integer of 0 or 1, and T represents a divalent hydrocarbon group having 1 to 10 carbon atoms which may be branched. )] |
