PROBLEM TO BE SOLVED: To provide an electrophotographic photoreceptor which suppresses a defective image due to charging irregularity or defective charging, to provide a manufacturing method of the electrophotographic photoreceptor, and to provide a process cartridge and an electrophotographic apparatus provided with the electrophotographic photoreceptor. SOLUTION: The electrophotographic photoreceptor comprises: a conductive supporting body; a photosensitive layer; and an intermediate layer disposed between the conductive supporting body and the photosensitive layer, wherein the intermediate layer contains metal oxide particles and at least one kind of compound selected from a group represented by formula (1), formula (2) and formula (3). The manufacturing method of the electrophotographic photoreceptor, and the process cartridge and the electrophotographic apparatus provided with the electrophotographic photoreceptor are provided too. In the formula (1), formula (2) and formula (3), Z11, Z12, Z21, Z22, Z31, Z32 are respectively independently oxygen atom, C(CN)<SB>2</SB>, N-R, C(CN)COR, C(CN)COOR, C(CN)R, C(COOR)<SB>2</SB>(R is an aryl group or an alkyl group which may have a substituent). X11 to X16, X21 to X25, X28, X31 to X36 are respectively independently hydrogen atom, halogen atom, hydroxyl group, nitro group, trifluoroalkyl group, alkoxy group which may have a substitute, or an alkyl group which may have a substitute.
