The present invention provides organophotoreceptors comprising 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;
Y1 and Y2 are, each independently, a phenothiazine group, a phenoxazine group, or a phenazine group;
R1, R2, R3, and R4 are, each independently, an alkyl group, an alkenyl group, a heterocyclic group, or an aromatic group; and
R5 and R6 are, 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, imaging methods and processes, and charge transport materials are also described.
