Electrophotographic photosensitive member, process cartridge, and electrophotographic apparatus

A process cartridge that is detachably attachable to an electrophotographic apparatus main body, and integrally supports:

• 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,
• wherein the electrophotographic photosensitive member comprises a support and a surface layer,
• the surface layer includes a cured product of a composition containing a curable hole-transport compound, a compound represented by the following formula (1), and a compound represented by the following formula (2),
• in the formula (1), Rf11 represents a divalent group having 3 or more carbon atoms and 6 or more fluorine atoms, R12 and R13 each independently represent a hydrogen atom a fluorine atom, an acryloyloxy group, or a methacryloyloxy group, with the proviso that at least one of R12 and R13 is an acryloyloxy group or a methacryloyloxy group,
• in the formula (2), R21 and R22 each independently represent an alkyl group having 1 or more and 4 or less carbon atoms or a substituted or unsubstituted aryl group having 1 or more and 4 or less carbon atoms, a substituent, which can be a substituent of the aryl group, is an alkyl group having 1 or more and 4 or less carbon atoms, R21 and R22 may be joined together to form a ring, R23 represents an alkyl group having 1 or more and 4 or less carbon atoms, R24 and R25 each independently represent a hydrogen atom or a methyl group, and R26 and R27 each independently represent an alkylene group having 1 or more and 4 or less carbon atoms.
