The present invention provides an organophotoreceptor comprising 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
X―Z―X'
where X and X' are, each independently, a (9-fluorenylidene)malononitrile group, and Z is a linking group having the formula -(CH2)m-, branched or linear, where m is an integer between 1 and 30, inclusive, and one or more of the methylene groups may be replaced by O, S, C=O, Si=O, S(=O)2, P(=O)2, an aromatic group, a heterocyclic group, an aliphatic cyclic group, a Si(R1)(R2) group, a BR3 group, a NR4 group, a CHR5 group, or a CR6R7 group where R1, R2, R3, R4, R5, R6, and R7 are, each independently, H, halogen, hydroxyl, thiol, an alkoxy group, an alkyl group, an alkenyl group, an aromatic group, a heterocyclic group, or a part of a cyclic ring; and
(b) a charge generating compound.
Corresponding electrophotographic apparatuses and imaging methods are described.
