(57) Abstract: To provide an electrophotographic photoreceptor having improved properties such as charging property, photosensitivity, and repeated stability. A conductive substrate has at least an undercoat layer and a photoconductive layer, and the undercoat layer contains at least one polyester compound having a repeating unit having a specific divalent group. In this undercoat layer, an electron-accepting compound, an electron-donating compound, an organic low-molecular compound such as an organometallic complex salt can be dispersed, and the polymer material forming the undercoat layer contains another repeating unit. It is preferably a polyester copolymer. Moreover, it is preferable that the photoconductive layer contains a phthalocyanine-based pigment as a charge generating substance. |
