Abstract

See full text

An electrophotographic apparatus includes a cylindrical electrophotographic photosensitive member, a charging roller that is disposed in contact with the electrophotographic photosensitive member and applies a direct current voltage to charge the electrophotographic photosensitive member, and a driving force transmission that transmits a driving force which causes rotation so that contact portions of the electrophotographic photosensitive member and the charging roller move in the same direction and the peripheral speed of the charging roller is higher than the peripheral speed of the electrophotographic photosensitive member, wherein the undercoat layer of the electrophotographic photosensitive member contains metal oxide and the undercoat layer has a volume resistivity of 1×107 Ω·cm or more and 1×1014 Ω·cm or less.
