Abstract:
Provided is an electrophotographic photosensitive member, including: a support; a charge-generating layer on the support; a charge-transporting layer on the charge-generating layer; and a protective layer on the charge-transporting layer, wherein the protective layer contains the following components (α), (β), and (γ): (α) a polymer of a hole-transportable compound; (β) a polycarbonate resin; and (γ) a hole-transportable compound, wherein a content of the component (β) in the protective layer is 0.01 mass % or more and 4.0 mass % or less with respect to a content of the component (α) in the protective layer, wherein a content of the component (γ) in the protective layer is 0.001 mass % or more and 3.0 mass % or less with respect to the content of the component (α) in the protective layer, and wherein the charge-transporting layer contains the component (γ).
