Abstract:
An electrophotographic photoreceptor includes a conductive substrate, and at least a photosensitive layer on the conductive substrate, a layer located at a surface of the photosensitive layer side of the electrophotographic photoreceptor contains fluorine containing resin particles and a fluoro graft polymer having a fluoroalkyl group having 1 to 7 carbon atoms, and an area for a polystyrene equivalent molecular weight of 700,000 or more is from about 5% to about 20% of the total area in a gel permeation chromatography (GPC) chart for the fluoro graft polymer.
