ABSTRACT:
An improved organophotoreceptor includes an electrically conductive substrate and a photoconductive element on the electrically conductive substrate where the photoconductive element comprises:a) a charge transport material having the following formula:where X is a linking group;Y1and Y2are, each independently, a phenothiazine group, a phenoxazine group, or a phenazine group;R1, R2, R3, and R4are, each independently, an alkyl group, an alkenyl group, a heterocyclic group, or an aromatic group; andR5and R6are, each independently, a hydrogen, an alkyl group, an alkenyl group, a heterocyclic group, or an aromatic group; and(b) a charge generating compound.Corresponding electrophotographic apparatuses and imaging methods are described.
