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, R4, R5, R6, R7, and R8 are, each independently, an alkyl group, an alkaryl group, an aryl group, or heterocyclic group, X and X′ are, each independently, aromatic groups, and Z is a divalent linking group; and (b) a charge generating compound. Corresponding electrophotographic apparatuses and imaging methods are described.
