PROBLEM TO BE SOLVED: To provide a highly sensitive electrophotographic photoreceptor where charge generation and movement of a hole and an electron are performed efficiently, the charge polarity is used at both positive/negative polarities, and a stable sensitivity characteristic is acquired for environmental variation. SOLUTION: This electrophotographic photoreceptor is provided with: a conductive support body; and a photosensitive layer disposed on the conductive support body. The photosensitive layer contains: a charge generator; diphenoquinone compound expressed by a general formula (1); and a hole transport agent of a specific distyryl structure. In general the formula (1), R<SB>1</SB>, R<SB>2</SB>and R<SB>3</SB>are saturated hydrocarbon, and may be the same mutually and different from each other. COPYRIGHT: (C)2011,JPO&INPIT |
