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 formulawhere R1, R2, R3, and R4comprise, each independently, an alkyl group, an alkenyl group, an aromatic group, a heterocyclic group, or a part of a ring group; X and X′ comprise, each independently, an aromatic group; Y and Y′ comprise, each independently, a (disubstituted)methylene group; and Z is a linking group; (b) a charge generating compound; and (c) an electrically conductive substrate on which said charge transport material and said charge generating compound are located. Corresponding electrophotographic apparatuses and imaging methods are also described.
