An electrophotographic photoreceptor includes a conductive substrate and a single-layered photosensitive layer formed so as to overlie the conductive substrate, the photosensitive layer containing a binder resin, a charge-generating material, a hole-transporting material, an electron-transporting material represented by General Formula (1), and at least one compound selected from a compound represented by General Formula (2) and a compound represented by General Formula (3). The amount of the at least one compound selected from the compound represented by General Formula (2) and the compound represented by General Formula (3) is in the range of approximately 10 parts by weight to 100 parts by weight in total relative to 100 parts by weight of the electron-transporting material represented by General Formula (1).
