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 a fluorine-based graft polymer and a fluorine-containing resin particle. The fluorine-based graft polymer includes at least a first structural unit that does not have an acidic group with a pKa of 3 or less but has a fluorine atom, a second structural unit derived from a macromonomer, and a third structural unit having the acidic group with a pKa of 3 or less.
