ABSTRACT:
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;R1and R2are, 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, urethane, urea, an ester group, a NR3group, a CHR4group, or a CR5R6group where R3, R4, R5, and R6are, independently, H, an alkyl group, an alkaryl group, a heterocyclic group, or an 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 NR7group where R7is hydrogen atom, an alkyl group, or aryl group, wherein Y has a structure selected to form n bonds with the corresponding X groups; andZ is a fluorenylidene group; and(b) a charge generating compound. Corresponding electrophotographic apparatuses and imaging methods are described.
