Claims5
An electrophotographic photosensitive member, comprising:
- a support and a protection layer as a surface layer of the electrophotographic photosensitive member,
- the protection layer being a cured film formed by polymerization of monomers contained in a composition, each of the monomers having a polymerizable functional group, the monomers consisting of a hole transporting compound represented by Formula (1-19) and compounds represented by Formulae (3-1), (4-21) and (6-1)
- wherein the only monomers in the composition are the compounds according to Formulae (1-19), (3-1), (4-21) and (6-1).
An electrophotographic apparatus, comprising:
- an electrophotographic photosensitive member, a charging unit, an exposing unit, a developing unit, and a transfer unit;
- the electrophotographic photosensitive member comprising a support and a protection layer as a surface layer of the electrophotographic photosensitive member, the protection layer being a cured film formed by polymerization of monomers contained in a composition, each of the monomers having a polymerizable functional group, the monomers consisting of a hole transporting compound represented by Formula (1-19) and compounds represented by Formulae (3-1), (4-21) and (6-1)
- wherein the only monomers in the composition are the compounds according to Formulae (1-19), (3-1), (4-21) and (6-1).
A process cartridge integrally supporting an electrophotographic photosensitive member and at least one unit selected from the group consisting of a charging unit, a developing unit, a transfer unit and a cleaning unit, and being detachably attachable to a main body of an electrophotographic apparatus;
- the electrophotographic photosensitive member comprising a support and a protection layer as a surface layer of the electrophotographic photosensitive member, the protection layer being a cured film formed by polymerization of monomers contained in a composition, each of the monomers having a polymerizable functional, the monomers consisting of a hole transporting compound represented by Formula (1-19) and compounds represented by Formulae (3-1), (4-21) and (6-1)
- wherein the only monomers in the composition are the compounds according to Formulae (1-19), (3-1), (4-21) and (6-1).
