Abstract
An electrophotographic photosensitive member having a support and a photosensitive layer on the support, wherein the electrophotographic photosensitive member comprises a surface layer comprising a polymerization product of a composition containing polyrotaxane and a charge transporting substance, and the polymerization product including a bond between the polyrotaxane and the charge transporting substance.
Claims7
An electrophotographic photosensitive member having a support and a photosensitive layer on the support, wherein
- the electrophotographic photosensitive member comprises a surface layer comprising a polymerization product of a composition containing polyrotaxane and a charge transporting substance, and
- the polymerization product includes a bond between the polyrotaxane and the charge transporting substance.
A process cartridge that integrally supports 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 and is detachably attachable to a main body of an electrophotographic image forming apparatus,
- the electrophotographic photosensitive member having a support and a photosensitive layer on the support, wherein
- the electrophotographic photosensitive member comprises a surface layer comprising a polymerization product of a composition containing polyrotaxane and a charge transporting substance, and
- the polymerization product includes a bond between the polyrotaxane and the charge transporting substance.
An electrophotographic image forming apparatus having an electrophotographic photosensitive member, a charging unit, an exposing unit, a developing unit, and a transfer unit,
- the electrophotographic photosensitive member having a support and a photosensitive layer on the support, wherein
