An 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 X comprises a linking group; R1 and R1′ comprise, each independently, H, an alkyl group, an alkenyl group, an alkynyl group, an aromatic group, or a heterocyclic group; and R2, R3, R2′, and R3′ comprise, each independently, an arylamine group; and (b) a charge generating compound. Corresponding electrophotographic apparatuses, imaging methods, and methods of forming the charge transport material are described.
