ABSTRACT:
An improved organophotoreceptor comprises 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 formulawhere X1and X2are, each independently, a bond or a linking group;Y comprises a bond or an arylamine group;Z comprises a bond, O, S, or NR4;R1and R4comprise, each independently, H, an alkyl group, an alkenyl group, an alkynyl group, an aromatic group, or a heterocyclic group;R2and R3comprise, each independently, an alkyl group, an alkenyl group, an alkynyl group, an aromatic group, or a heterocyclic group; andn is a distribution of integers between 1 and 100,000 with an average value of greater than one; and(b) a charge generating compound.Corresponding electrophotographic apparatuses, imaging methods, and methods of forming the charge transport material are described.
