Abstract
According to the present invention, there is provided: an electrophotographic photosensitive member having a photosensitive layer on a support in which a surface layer of the electrophotographic photosensitive member comprises an acrylic polymer having a polyfluoroolefin unit and an alkylene oxide unit, and having a number-average molecular weight in a range of 2,000 to 20,000; a process cartridge and an electrophotographic apparatus both comprising the electrophotographic photosensitive member.
Claims19
An electrophotographic photosensitive member comprising a photosensitive layer on a support,
- wherein a surface layer of the electrophotographic photosensitive member comprises an acrylic polymer having a polyfluoroolefin unit and an alkylene oxide unit, and having a number-average molecular weight in a range of 2,000 to 20,000.
A process cartridge that integrally supports an electrophotographic photosensitive member comprising a photosensitive layer on a support 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 that is detachably attached to an electrophotographic apparatus,
- wherein a surface layer of the electrophotographic photosensitive member comprises an acrylic polymer having a polyfluoroolefin unit and an alkylene oxide unit, and having a number-average molecular weight in a range of 2,000 to 20,000.
An electrophotographic apparatus having:
- an electrophotographic photosensitive member having a photosensitive layer on a support;
- a charging unit;
- an exposing unit;
- a developing unit;
- and a transfer unit;
- wherein a surface layer of the electrophotographic photosensitive member comprises an acrylic polymer having a polyfluoroolefin unit and an alkylene oxide unit, and having a number-average molecular weight in a range of 2,000 to 20,000.
