Abstract
An electrophotographic photoreceptor includes a conductive substrate and a photosensitive layer disposed on the conductive substrate. An outermost surface layer of the electrophotographic photoreceptor contains fluorine-containing resin particles and a fluorine-containing graft polymer having a structural unit represented by general formula (FA), a structural unit represented by general formula (FB), and a structural unit represented by general formula (FC): where RF1, RF2, RF3, and RF4 each independently represent a hydrogen atom or an alkyl group; XF1 represents an alkylene chain, a halogen-substituted alkylene chain, —S—, —O—, —NH—, or a single bond; YF1 represents an alkylene chain, a halogen-substituted alkylene chain, —(CfxH2fx-1(OH))—, or a single bond; QF1 represents —O— or —NH—; fl, fm, and fn each independently represent an integer of 1 or more; fp, fq, fr, and fs each independently represent an integer of 0 or 1 or more; ft represents an integer of 1 or more and 7 or less; fx represents an integer of 1 or more; RF5 and RF6 each independently represent a hydrogen atom or an alkyl group; and fz represents an integer of 1 or more.
