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).

Claim (Index 8):
A process cartridge, comprising:\n an electrophotographic photosensitive member; and at least one unit selected from the group consisting of a charging unit, a developing unit, and a cleaning unit, the process cartridge integrally supporting the electrophotographic photosensitive member and the at least one unit, and being removably mounted onto a main body of an electrophotographic apparatus, wherein the electrophotographic photosensitive member includes 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 (\u03b1), (\u03b2), and (\u03b3):\n (\u03b1) a polymer of a hole-transportable compound represented by the following formula (A); \n (\u03b2) a polycarbonate resin having a structural unit represented by the following formula (B); and \n (\u03b3) a hole-transportable compound represented by the following formula (C), \n wherein a content of the component (\u03b2) in the protective layer is 0.01 mass % or more and 4.0 mass % or less with respect to a content of the component (\u03b1) in the protective layer, wherein a content of the component (\u03b3) in the protective layer is 0.001 mass % or more and 3.0 mass % or less with respect to the content of the component (\u03b1) in the protective layer, and wherein the charge-transporting layer contains the component (\u03b3): in the formula (A), Z 1  to Z 3  each independently represent a substituted or unsubstituted aryl group, and a substituent of the aryl group comprises a linear or branched alkyl group having 1 or more and 6 or less carbon atoms, a halogen atom, or a polymerizable functional group, provided that the hole-transportable compound represented by the formula (A) has one or more polymerizable functional groups each serving as the substituent; in the formula (B), R 11  to R 14  each independently represent a hydrogen atom, a methyl group, or an ethyl group, and X l  represents a single bond, an oxygen atom, or a divalent hydrocarbon group; in the formula (C), Ar 1  and Ar 2  each independently represent a substituted or unsubstituted phenyl group, Ar 3  represents an n-valent aromatic group, and n represents an integer of 1 or more and 3 or less.
