Polymeric charge transport compositions for organophotoreceptors

摘要

This invention includes an organophotoreceptor having an electrically conductive substrate and photoconductive element on the electrically conductive substrate, the photoconductive element having a) a polymeric charge transport composition with the formula where Y₁ and Y₂ are, each independently, a bond, a -CR₁-N-NR₂- group, or a -CR₃-N-N-CR₄- group; R, R', R'', R₁, R₂, R₃, and R₄ comprise, each independently, H, an alkyl group, an alkenyl group, a heterocyclic group, an aromatic group, or a part of a ring group; X₁ and X₂ are, each independently, a linking group; T₂ comprises a thiiranyl group, H, an alkyl group, an alkenyl group, or an aromatic group; Ar comprises an aromatic group; Z is a bridging group; and n is a distribution of integers between 1 and 100,000 with an average value at least 2; and (b) a charge generating compound. Corresponding electrophotographic apparatuses and imaging processes are also described.
