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 where R1, R2, R3, and R4 are, independently, an alkyl group, an alkaryl group, an aryl group, or a part of a cyclic group; R5 is hydrogen, an alkyl group, an alkaryl group, an aryl group, or a heterocyclic group; X comprises an aromatic group, such as an aryl group or an aromatic heterocyclic group; Y is a linking group; and Z comprises an epoxy group; and (b) a charge generating compound. Corresponding electrophotographic apparatuses and imaging methods are described.
