Abstract:
The present invention relates to an electrophotographic photosensitive member in which a surface layer contains a polymer of a hole transport material having a polymerizable functional group, and the hole transport material has a specific fluorene structure.

Claim (Index 7):
An electrophotographic apparatus comprising an electrophotographic photosensitive member; and at least one unit selected from a charging unit, an exposing unit, a developing unit, a transfer unit, and a cleaning unit, wherein\n the electrophotographic photosensitive member comprises a support and a photosensitive layer on the support, and a surface layer of the electrophotographic photosensitive member contains a polymer of a hole transport compound represented by Formula (1) below, (where the hole transport compound represented by Formula (1) has at least one monovalent polymerizable functional group, in Formula (1), R 1  and R 2  each independently represent a hydrogen atom, a fluorine atom, an alkyl group, a fluorine atom-substituted alkyl group, a phenyl group-substituted alkyl group, a phenyl group, or an alkyl group-substituted phenyl group, or an alkyl group having a monovalent polymerizable functional group as a substituent, a phenyl group-substituted alkyl group having a monovalent polymerizable functional group as a substituent, a phenyl group having a monovalent polymerizable functional group as a substituent, or an alkyl group-substituted phenyl group having a monovalent polymerizable functional group as a substituent, R 3  and R 4  each independently represent a hydrogen atom, an alkyl group, an alkoxy group, or a phenyl group, or an alkyl group having a monovalent polymerizable functional group as a substituent, or an alkoxy group having a monovalent polymerizable functional group as a substituent, or a phenyl group having a monovalent polymerizable functional group as a substituent, Ar 1  and Ar 2  each independently represent a single bond, an arylene group, and an alkyl group-substituted arylene group, n represents an integer of 1 or more to 5 or less, when n is 2 or more, structures in parentheses may be the same as or different from each other, at least one of n R 1  and n R 2  is a fluorine atom or a fluorine atom-substituted alkyl group, Z 1  represents a monovalent group represented by Formula (2) below, Z 2  represents a hydrogen atom or a monovalent group represented by Formula (2) below, when Z 2  is a monovalent group represented by Formula (2) below, Z 1  and Z 2  may be the same as or different from each other, in Formula (2), * represents a bonding position at which Ar 1  or Ar 2  is bonded, and Ar 11  and Ar 12  each independently represent an aryl group, an alkyl group-substituted aryl group, an alkoxy group-substituted aryl group, or an aryl group having a monovalent polymerizable functional group as a substituent, an alkyl group-substituted aryl group having a monovalent polymerizable functional group as a substituent, or an alkoxy group-substituted aryl group having a monovalent polymerizable functional group as a substituent).
