PROBLEM TO BE SOLVED: To provide an electrophotographic photoreceptor high in sensitivity and low in residual potential and stable to ozone, light and heat in an early stage and small in deterioration due to fatigue in repeated uses by using speci fied organic compounds as charge transfer substance and combining them with an oxidation preventive agent. SOLUTION: This electrophotographic photoreceptor is provided on a conductive substrate with photosensitive laminated layers of a charge generating layer and a charge transfer layer or a bifunctional single layer containing the antioxidant and the amine compound represented by the formula in which Ar1 is an optionally substituted aryl group; Ar2 is an optionally substituted phenylene, naphthylene, biphenylene, or anthrylene group; R1 is an H atom or a lower alkyl or lower alkoxy group; X is an H atom, an optionally substituted alkyl or such aryl group; and Y is an optionally substituted aryl group.
