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 fluorinated alkyl group. In an infrared absorption spectrum of the fluorine-containing graft polymer, a ratio of a peak area in a wavenumber range of from 1,020 cm−1 to 1,308 cm−1 to a peak area in a wavenumber range of from 1,673 cm−1 to 1,779 cm−1 is 2.7 or more and 4.8 or less.
