Abstract
An electrophotographic photoreceptor includes: a conductive base body and a photosensitive layer, in which an outermost surface layer of the electrophotographic photoreceptor contains fluorine-containing resin particles, and in which a fluorine atom concentration at a surface of the outermost surface layer is 1.5 to 5.0 times a fluorine atom concentration at a depth of 1 μm from the surface of the outermost surface layer, or in which a number density ratio of aggregates of the fluorine-containing resin particles in a second region defined in this specification, to aggregates of he fluorine-containing resin particles in a first region defined in this specification is less than 0.95, and a ratio of an area ratio of the fluorine-containing resin particles in the second region, to an area ratio of the flourine-containing resin particles in the first region is within a range of 1±0.1.
