An electrophotographic photoreceptor is provided that contains a conductive substrate, an undercoat layer, a charge generation layer, and a charge transport layer, wherein the under coat layer contains a binder resin and multiple inorganic pigments each having different average primary particle diameters in a total amount of from 75 to 86% by weight, the charge generation layer contains a binder resin and a titanyl phthalocyanine pigment having a specific X-ray diffraction spectrum in an amount of from 70 to 85% by weight, the charge transport layer comprises a specific distyryl compound, and the following formulae (2-1) to (2-3) are satisfied: 0.2D(F2)/D(G)) 0.2D(F1) (2-2) D(F2)D(F1) (2-3) wherein D(F1) (mum) and D(F2) (mum) represent average primary particle diameters of the largest and smallest inorganic pigments, respectively, and D(G) (mum) represents an average primary particle diameter of the titanyl phthalocyanine pigment.
