Abstract
Provided is an electrophotographic photosensitive member having a satisfactory suppressing effect on image smearing. The electrophotographic photosensitive member includes: a support; a photosensitive layer; and a surface layer, the surface layer containing at least one of melamine resin-containing particles and acrylic resin-containing particles, and a polymerized product of a composition containing a charge-transporting compound having a polymerizable functional group; and a compound represented by formula (1):
Claims10
An electrophotographic photosensitive member comprising:

- 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,
- wherein the electrophotographic photosensitive member includes a support, a photosensitive layer, and a surface layer, and
- wherein the surface layer contains
- at least one of melamine resin-containing particles or acrylic resin-containing particles;
- and
- a polymerized product of a composition containing
- a charge-transporting compound having a polymerizable functional group;
- and
- a compound represented by formula (1):
- in the formula (1), R11 and R12 each independently represent an alkyl group having 1 or more and 4 or less carbon atoms, or a substituted or unsubstituted aryl group, and R11 and R12 may be bonded to each other to form an aliphatic ring, R13 represents an alkyl group having 1 or more and 4 or less carbon atoms, R14 and R15 each independently represent a hydrogen atom or a methyl group, and R16 and R17 each independently represent an alkylene group having 1 or more and 4 or less carbon atoms.
An electrophotographic apparatus comprising:
- an electrophotographic photosensitive member, a charging unit, an exposing unit, a developing unit, and a transferring unit,
- wherein the electrophotographic photosensitive member includes a support, a photosensitive layer, and a surface layer, and
- wherein the surface layer contains
- at least one of melamine resin-containing particles and acrylic resin-containing particles:
- and
- a polymerized product of a composition containing:
- a charge-transporting compound having a polymerizable functional group;
- and
- a compound represented by formula (1):
- in the formula (1), R11 and R12 each independently represent an alkyl group having 1 or more and 4 or less carbon atoms, or a substituted or unsubstituted aryl group, and R11 and R12 may be bonded to each other to form an aliphatic ring, R13 represents an alkyl group having 1 or more and 4 or less carbon atoms, R14 and R15 each independently represent a hydrogen atom or a methyl group, and R16 and R17 each independently represent an alkylene group having 1 or more and 4 or less carbon atoms.
