Patent ID: 7659044

Claim:
A photoconductor comprising: an electrically conductive support, and a photosensitive layer disposed on the support, wherein the photosensitive layer comprises a crosslinked layer and the crosslinked layer is produced by curing a dispersion in which an acryl-modified polyorganosiloxane having an imide structure or an amide structure or an acryl-modified polyorganosiloxane having both a radical reactivity and an imide structure or an amide structure is dispersed in a radical polymerizable monomer; and each of the acryl-modified polyorganosiloxane having an imide structure or an amide structure and the acryl-modified polyorganosiloxane having both a radical reactivity and an imide structure or an amide structure is an emulsion graft copolymer of a polyorganosiloxane represented by the following formula (1), a (meth)acrylate ester represented by the following formula (2), and a copolymerizable monomer having an imide or an amide group: wherein each of R 1 , R 2 and R 3 represent a C 1 to C 20 hydrocarbon group or halogenated hydrocarbon group; Y represents an organic group having a radical reactive group, a SH group, or both a radical reactive group and a SH group; u is a positive integer of 10,000 or less and v is an integer of 1 or more; and Z 1 and Z 2 represent a hydrogen atom, a lower alkyl group or a triorganosilyl group represented by the following formula: wherein R 4 and R 5 represent a C 1 to C 20 hydrocarbon group or a halogenated hydrocarbon group; and R 6 represents a C 1 to C 20 hydrocarbon group, a halogenated hydrocarbon group or an organic group having a radical reactive group, a SH group, or both a radical reactive group and a SH group, wherein R 7 represents a hydrogen atom or a methyl group; and R 8 represents an alkyl group, an alkyl group substituted by an alkoxy group, a cycloalkyl group or an aryl group, said imide structure is derived from a monomer having a hexahydrophthalimide structure represented by formula (A) and said amide structure is derived from a monomer having a N-(1,1-dimethyl-3-oxobutyl)acrylamide structure represented by formula (B)
