Abstract
An electrophotographic photosensitive member, process cartridge and electrophotographic apparatus which use the same photosensitive member, and process for producing the same photosensitive member. The electrophotographic photosensitive member, includes a support and photosensitive layer thereon, wherein said photosensitive layer contains at least one of a hole-transporting compound with two or more chain-polymerizing functional groups in the same molecule and the compound hardened by polymerizing or cross-linking the above hole-transporting compound.
Claims32
An electrophotographic photosensitive member, comprising a support and photosensitive layer thereon, wherein said photosensitive layer contains at least one of a hole-transporting compound with two or more chain-polymerizing functional groups in the same molecule and the compound hardened by polymerizing or cross-linking the above hole-transporting compound.
A process cartridge comprising an electrophotographic photosensitive member and at least one of the means selected from the group consisting of those for electrification, development and cleaning,
- wherein said electrophotographic photosensitive member and at least one of said means are monolithically supported to form an assembly freely attachable to or detachable from an electrophotographic apparatus body, and
- said electrophotographic photosensitive member comprises a support and photosensitive layer thereon, said photosensitive layer containing at least one of a hole-transporting compound with two or more chain-polymerizing functional groups in the same molecule and the compound hardened by polymerizing or cross-linking the above hole-transporting compound.
An electrophotographic apparatus comprising an electrophotographic photosensitive member, and means for electrification, exposure, development and transferring,
- said electrophotographic photosensitive member comprising a support and photosensitive layer thereon,
- wherein said photosensitive layer contains at least one of a hole-transporting compound with two or more chain-polymerizing functional groups in the same molecule and the compound hardened by polymerizing or cross-linking the above hole-transporting compound.
A process for producing an electrophotographic photosensitive member which has a support and photosensitive layer thereon, comprising a step for forming a photosensitive layer for said electrophotographic photosensitive member,
- wherein said step hardens a hole-transporting compound with two or more chain-polymerizing functional groups in the same molecule by polymerization or cross-linking.
