The present invention provides organophotoreceptors comprising annelectrically conductive substrate and. a photoconductive element on the electricallynconductive substrate, the photoconductive element comprising:n (a) a charge transport material having the formulan n where Y 1 and Y 2 are, each independently, an arylamine group; n R 1 and R 2 comprise, each independently, H, an alkyl group, an alkenyl group,na heterocyclic group, or an aromatic group; n X 1 and X 2 , each independently, are bridging groups; n E 1 and E 2 are, each independently, an epoxy group; and n Z is a linking group comprising an alkyl group, an alkenyl group, a heterocyclicngroup, or an aromatic group; and (b) a charge generating compound. n The charge transport materials can be crosslinked to a polymeric binder, eitherndirectly or through a crosslinking agent. Corresponding electrophotographicnapparatuses and imaging methods (processes) are described, as are correspondingncharge transport materials. |
