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 R 1 , R 2 , R 3 , R 4 , R 5 , R 6 , R 7 , and R 8 , are, each independently, an alkyl group, an alkenyl group, an alkynyl group, an aryl group, or a heterocyclic group;
   R 9 and R 10 are, each independently, H, an alkyl group, an alkenyl group, an alkynyl group, an aryl group, or a heterocyclic group;
   Ar 1 and Ar 2 are, each independently, an aromatic group;
   Y is an arylamine group; and
   X 1 and X 2 are, each independently, a linking group; and
(b) a charge generating compound.

Corresponding electrophotographic apparatuses and imaging methods (processes) are described, as are charge transport materials.
