In an electrophotographic photoreceptor in which an undercoating layer and a photosensitive layer are provided on a conductive substrate, the undercoating layer preferably contains at least one electron transporting pigment and a reactive organometallic compound, the electron transporting pigment being selected from a group consisting of an electron transporting polycyclic quinone pigment such as brominated anthoanthrone, an electron transporting perylene pigment, an electron transporting phthalocyanine pigment, and an electron transporting azo pigment, and the surface of the electrophotographic photoreceptor contains at least one resin selected from electric charge transporting polycarbonate and electric charge transporting polyester. As a result, it is possible to provide an electrophotographic organic photoreceptor having stabilized performance and durability, which is not affected by environmental changes even when used for a long period of time and in which deterioration of the performance and electric characteristics thereof is prevented.
