Patent ID: 8546052

Claim:
An electrophotographic photosensitive member that comprises a surface layer containing a polymeric product obtained by polymerized composition consisting of an adamantane compound represented by the following general formula (1) and a charge-transporting compound having a chain polymerizable functional group: wherein R 1 to R 6 each independently represent a hydrogen atom, an alkyl group, a haloalkyl group, a hydroxyl group, an alkoxyl group, an amino group, an alkylamino group, a trialkylsilyl group or a halogen atom; and X 1 to X 10 each independently represent a hydrogen atom, an alkyl group, a haloalkyl group, a hydroxyl group, an alkoxyl group, an amino group, an alkylamino group, a trialkylsilyl group, a halogen atom or an organic group having a chain polymerizable functional group, and wherein R 1 and X 1 may combine to form an oxo group (═O), R 2 and X 2 may combine to form an oxo group (═O), R 3 and X 3 may combine to form an oxo group (═O), R 4 and X 4 may combine to form an oxo group (═O), R 5 and X 5 may combine to form an oxo group (═O) and R 6 and X 6 may combine to form an oxo group (═O), provided that at least two of X 1 to X 10 are organic groups having chain polymerizable functional groups, and, when X 1 is an organic group having a chain polymerizable functional group, R 1 is a hydrogen atom, when X 2 is an organic group having a chain polymerizable functional group, R 2 is a hydrogen atom, when X 3 is an organic group having a chain polymerizable functional group, R 3 is a hydrogen atom, when X 4 is an organic group having a chain polymerizable functional group, R 4 is a hydrogen atom, when X 5 is an organic group having a chain polymerizable functional group, R 5 is a hydrogen atom, and when X 6 is an organic group having a chain polymerizable functional group, R 6 is a hydrogen atom.
