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 formula ##STR00001## where Y.sub.1 and Y.sub.2 are, each independently, an arylamine group; R.sub.1 and R.sub.2 comprise, each independently, H, an alkyl group, an alkenyl group, a heterocyclic group, or an aromatic group; X.sub.1 and X.sub.2, each independently, are bridging groups; E.sub.1 and E.sub.2 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 bind, either directly or through a crosslinking agent. Corresponding electrophotographic apparatuses and imaging methods are described.
