Embodiment

[0505] Example photosensitive member 1

[0506] A cylindrical aluminum cylinder having an outer diameter of 30 mm, a length of 357.5 mm, and a thickness of 0.7 mm was used as a support (conductive support).

[0507] Next, 10 parts of zinc oxide particles (specific surface area: 19m 2 / g, powder resistivity: 4.7×10 6 Ω·cm) was mixed with 50 parts of toluene, and 0.08 parts of a silane coupling agent was added to the mixture, followed by stirring for 6 hours. Thereafter, toluene was removed by distillation under reduced pressure and the residue was dried by heating at 130° C. for 6 hours, thereby obtaining surface-treated zinc oxide particles. KBM602 (compound name: N-2-(aminoethyl)-3-aminopropylmethyldimethoxysilane) manufactured by Shin-Etsu Chemical Co., Ltd. was used as a silane coupling agent.

[0508]Next, 15 parts of polyvinyl butyral resin (weight average molecular weight: 40,000, trade name: BM-1, manufactured by SEKISUICHEMICAL CO., LTD.) and 15 parts of blocked iso...

Abstract

Provided are an electrophotographic photosensitive member that satisfies abrasion resistance and electrical characteristics, and satisfactorily suppresses image deletion, and a process cartridge and an electrophotographic apparatus each including the electrophotographic photosensitive member. The electrophotographic photosensitive member includes a surface layer including a polymerization product of a hole-transporting substance having a reactive functional group, wherein the structure of the hole-transporting substance other than the reactive functional group is one of the following: composed of carbon atoms and hydrogen atoms Composed structure, and a structure composed of carbon atoms, hydrogen atoms, and oxygen atoms; and the structure of the hole-transporting substance other than the reactive functional group includes a specific conjugated structure.

Description

technical field [0001] The present invention relates to an electrophotographic photosensitive member, and a process cartridge and an electrophotographic apparatus each including the electrophotographic photosensitive member. The present invention also relates to novel fused polycyclic aromatic compounds. Background technique [0002] The surface layer of an electrophotographic photosensitive member is required to have abrasion resistance and chemical stability because stress generated by a series of electrophotographic processes including charging, exposure, development, transfer, and cleaning is repeatedly applied to the surface layer. [0003] A method for improving abrasion resistance is, for example, a method involving introducing a curable resin into the surface layer of an electrophotographic photosensitive member. However, when a surface layer having high abrasion resistance is provided, the surface layer is hardly worn, and therefore, the surface of the surface laye...
