The electrophotographic photoreceptor includes: an electrically conductive substrate; a charge generating layer formed on the electrically conductive substrate and comprising μ-oxo-gallium phthalocyanine dimer as a charge generating material dispersed in a binder resin; and a charge transporting layer formed on the charge generating layer. The charge transporting layer includes a charge transporting material and a binder resin. The charge transporting material is a combination of (1) a butadiene-based amine compound and a hydrazone compound and (2) a combination of a first benzidine compound and a second benzidine compound. The amount of the charge transporting material is 5-200 parts by weight based on 100 parts by weight of the binder resin of the charge transporting layer. The electrophotographic photoreceptor has an excellent electrostatic property and a high interlayer adhesive force and resistance to abrasion and can be manufactured at a low cost.
