PROBLEM TO BE SOLVED: To provide a lamination-type electrophotographic photoreceptor that can be provided with abrasion resistance while maintaining excellent electrical characteristics of the whole photoreceptor.SOLUTION: An electrophotographic photoreceptor includes a photosensitive layer. The photosensitive layer is: a lamination-type photosensitive layer laminated with a charge generation layer containing a charge generation agent and a charge transport layer containing a hole transport agent, a binder resin, a phthalocyanine pigment, and silica particles; or a single layer-type photosensitive layer containing a charge generation agent, a hole transport agent, a binder resin, a phthalocyanine pigment, and silica particles. The charge transport layer is located on the outermost surface of the lamination-type photosensitive layer. The content of silica particles is 0.5 pt.mass or more and 15 pts.mass or less with respect to 100 pts.mass of the binder resin. |
