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 Y1and Y2are, each independently, an arylamine group;R1and R2comprise, each independently, H, an alkyl group, an alkenyl group, a heterocyclic group, or an aromatic group;X1and X2, each independently, are bridging groups;E1and E2are, each independently, an epoxy group; andZ is a linking group comprising an alkyl group, an alkenyl group, a heterocyclic group, or an aromatic group; and(b) a charge generating compound.The charge transport materials can be crosslinked to a polymeric bind, either directly or through a crosslinking agent. Corresponding electrophotographic apparatuses and imaging methods are described.
