The present invention provides organophotoreceptors comprising 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 n is an integer between 3 and 6;
R1 and R2 are, each independently, H, an alkyl group, an alkenyl group, an aromatic group, or a heterocyclic group;
R3, R4, and R5 are, each independently, H, thiol, hydroxyl, carboxyl, an amino group, a halogen, nitro, cyano, an alkyl group, an alkenyl group, an aromatic group, a heterocyclic group, or a part of a ring group;
X1 and X2 are, each independently, a linking group;
Y comprises an arylamine group; and
Z is a bridging group; and
(b) a charge generating compound.
Corresponding electrophotographic apparatuses and imaging methods (processes) are described, as are corresponding charge transport materials.
