ORGANOPHOTORECEPTOR WITH A CHARGE TRANSPORT MATERIAL HAVING TWO EPOXIDATED-HYDRAZONE GROUPS, A METHOD FOR PREPARING THE SAME AND A METHOD FOR USING THE SAME

摘要

The present invention provides organophotoreceptors 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 CHEM where Y1 and Y2 are, each independently, an arylamine group; R1 and R2 comprise, each independently, H, an alkyl group, an alkenyl group, a heterocyclic group, or an aromatic group; X1 and X2, each independently, are bridging groups; E1 and E2 are, each independently, an epoxy group; and Z 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 binder, either directly or through a crosslinking agent. Corresponding electrophotographic apparatuses and imaging methods (processes) are described, as are corresponding charge transport materials.
