Patent ID: 7838188

Claim:
An electrophotographic photoconductor, comprising: a layer containing a hardened material, wherein the hardened material is prepared by polymerizing (A) a chain-polymerizable group-containing tertiary amine compound in which at least one alkyl group is bound to a nitrogen atom constituting an amine structure through chain polymerization; wherein the chain-polymerizable group-containing tertiary amine compound in which at least one alkyl group is bound to a nitrogen atom constituting an amine structure is a compound represented by any one of the Structural Formulas (2) and (2′), where R 1 and R 2 may be same to each other or different from each other and respectively represent any one of an alkyl group that may have a substituent group, an aromatic hydrocarbon group that may have a substituent group, a group represented by the following Structural Formula (1-1), and a group represented by the following Structural Formula (1-2), R 1 and R 2 may be bound together to form a heterocyclic ring, and the heterocyclic ring may be further substituted by a substituent group; R 4 represents any one of a hydrogen atom and a methyl group; Ar represents an aromatic hydrocarbon divalent group that may have a substituent group; “m” and “n” are respectively an integer of 0 to 6, and when “n” is equal to zero, any one of R 1 and R 2 represents the alkyl group that may have a substituent group or the group represented by the Structural Formula (1-2), where R 5 and R 6 may be same to each other or different from each other and respectively represent any one of an alkyl group that may have a substituent group and an aromatic hydrocarbon group that may have a substituent group; and R 7 represents any one of an alkylene group that may have a substituent group, an aromatic hydrocarbon divalent group that may have a substituent group, and a divalent group that is a combination thereof.
