| 1. An organophotoreceptor comprising an electrically conductive substrate and a photoconductive element on the electrically
conductive substrate, the photoconductive element comprising:
a charge transport material having the formula
 where Y comprises an aromatic heterocyclic group;
X is a bond or a linking group;
E comprises a reactive ring group, a reactive functional group, or an ethylenically unsaturated group; and
R1, R2, R3, and R4 comprise, each independently, H, an alkyl group, an acyl group, an ether group, an alkenyl group, an alkynyl group, a heterocyclic
group, an aromatic group, or a part of a ring group; and
(b) a charge generating compound.
