Patent ID: 7763406

Claim:
An electrophotographic photoreceptor comprising: at least an undercoat layer having a thickness of 15 μm or more; and a photosensitive layer on a conductive substrate, wherein the undercoat layer comprises a binder resin and contains metal oxide fine particles and an electron acceptor compound having a group reactive with the metal oxide fine particles, wherein the electron acceptor compound is one or more compounds selected from the group consisting of 1 hydroxyanthraquinone, purpurin, and aminohydroxyanthraquinone compounds, and wherein the metal oxide fine particles are surface-treated with a coupling agent, and are selected from the group consisting of titanium oxide, zinc oxide, tin oxide, and zirconium oxide, and wherein the electrophotographic photoreceptor comprises fluorinated resin particles in an outermost layer of the electrophotographic photoreceptor.
