Patent ID: 7452640

Claim:
An electrophotographic photoconductor for liquid development, comprising: a support; and a photosensitive layer on or above the support, wherein the photosensitive layer comprises a charge-generating material, a charge-transporting material and an acceptor compound, wherein the charge-transporting material comprises a charge-transporting polymer represented by the following General Formula (1): where, in the General Formula (1), R 1 and R 2 may be the same or different and represent an unsubstituted or substituted aryl group; Ar 1 , Ar 2 , and Ar 3 may be the same as or different from each other and represent an unsubstituted or substituted arylene group; “k” and “j” represent a composition ratio and 0.1≦k≦1, 0≦j≦0.9; “n” represents a recurring unit and is an integer of 5 to 5,000; “X” represents a divalent aliphatic group, a divalent cyclic aliphatic group, or a divalent group represented by the following General Formula (A): where, in the General Formula (A), R 11 and R 12 may be the same or different and represent an unsubstituted or substituted alkyl group, an unsubstituted or substituted aryl group, or a halogen atom; “l” and “m” represents an integer of 0 to 4; “Y” represents a single bond, a straight, branched, or cyclic alkylene group having a carbon number of 1 to 12, —O—, —S—, —SO—, —SO 2 —, —CO—, —CO—O-Z-O—CO— (in the formula, “Z” represents a divalent aliphatic group), or a group represented by the following General Formula (B): where, in the General Formula (B), “a” represents an integer of 1 to 20, and “b” represents an integer of 1 to 2,000; and R 21 and R 22 may be the same or different and represent an unsubstituted or substituted alkyl group, or unsubstituted or substituted aryl group.
