Patent ID: 7291433

Claim:
An organophotoreceptor comprising an electrically conductive substrate and a photoconductive element on the electrically conductive substrate, the photoconductive element comprising: (a) a charge transport material comprising a polymer having the formula: where X 1 and X 2 are, each independently, a bond or a linking group; Y comprises a bond or an arylamine group; Z comprises O, S, or NR 4 ; R 1 and R 4 comprise, each independently, H, an alkyl group, an alkenyl group, an alkynyl group, an aromatic group, or a heterocyclic group; R 2 and R 3 comprise, each independently, an alkyl group, an alkenyl group, an alkynyl group, an aromatic group, or a heterocyclic group; and n is a distribution of integers between 1 and 100,000 with an average value of greater than one; and (b) a charge generating compound.
