(57) [Summary] An electron capable of preventing interference fringes without impairing electrophotographic characteristics, controlling the infrared reflectance of a photoconductor, and improving the detection accuracy of an optical density sensor. Provide a photoreceptor. SOLUTION: In an electrophotographic photoreceptor having at least an undercoat layer and a photosensitive layer on a conductive support, the undercoat layer contains a naphthalocyanine compound represented by the following general formula (1). An electrophotographic photosensitive member characterized by the following. (In the formula (1), M represents two hydrogen atoms or a metal atom, and the metal atom may have a ligand. X 1 , X 2 , X 3 and X 4 each represent a hydrogen atom or a substituent. ) |
