Claims15
An electrophotographic photoreceptor comprising:
- a conductive substrate;
- and
- a photosensitive layer on the conductive substrate,
- wherein an outermost surface layer of the electrophotographic photoreceptor is formed of a layer-shaped article,
- the layer-shaped article comprising a fluorine-containing resin particle,
- the fluorine-containing resin particle comprising:
- 7 or more and 30 or less carboxyl groups per 106 carbon atoms;
- and
- 0 ppm or more and 3 ppm or less of a basic compound,
- the fluorine-containing resin particles are selected from the group consisting of polytetrafluoroethylene (PTFE) particles, tetrafluoroethylene-hexafluoropropylene copolymer (FEP) particles, tetrafluoroethylene-perfluoro(alkyl vinyl ether) copolymer (PFA) particles, ethylene-tetrafluoroethylene copolymer (ETFE) particles, and ethylene-chlorotrifluoroethylene copolymer (ECTFE) particles, and
- the basic compound is an amine compound.
