Improved organophotoreceptor comprises an electrically conductive substrate and a photoconductive element on the electrically conductive substrate, the photoconductive element comprising: (a) a charge transport material having the formula where n is an integer between 2 and 6, inclusive; R1 and R2 are, independently, H, an alkyl group, an alkaryl group, a heterocyclic group, or an aryl group; R3 and R4 are, independently, H, halogen, carboxyl, hydroxyl, thiol, cyano, nitro, aldehyde group, ketone group, an ether group, an ester group, a carbonyl group, an alkyl group, an alkaryl group, or an aryl group; X is a linking group having the formula -(CH2)m-, branched or linear, where m is an integer between 0 and 20, inclusive, and one or more of the methylene groups can be optionally replaced by O, S, C=O, O=S=O, a heterocyclic group, an aromatic group, urethane, urea, an ester group, a NR5 group, a CHR6 group, or a CR7R8 group where R5, R6, R7, and R8 are, independently, H, an alkyl group, an alkaryl group, a heterocyclic group, or an aryl group; and Y is a bond, C, N, O, S, a branched or linear -(CH2)p- group where p is an integer between 0 and 10 and where one or more of the hydrogen atoms in the -(CH2)p- may be optionally removed to provide bond positions to enable n to have a higher value than 2, an aromatic group, a cycloalkyl group, a heterocyclic group, or a NR9 group where R9 is hydrogen atom, an alkyl group, or aryl group Y comprises a bond, C, N, O, S, a branched or linear -(CH2)p- group where p is an integer between 0 and 10, an aromatic group, a cycloalkyl group, a heterocyclic group, or a NR9 group where R9 is hydrogen atom, an alkyl group, or aryl group, wherein Y has a structure selected to form n bonds with the corresponding X groups; and (b) a charge generating compound. Corresponding electrophotographic apparatuses and imaging methods are described.
