A POLYMERIC CHARGE TRANSPORT MATERIALS, AN ORGANOPHOTORECEPTOR COMPRISING THE SAME, AN ELECTROPHOTOGRAPHIC IMAGING APARATUS COMPRISING THE ORGANOPHOTORECEPTOR AND AN ELECTROPHOTOGRAPHIC IMAGING PROCESS USING THE ORGANOPHOTORECEPTOR

摘要

Improved organophotoreceptor comprises an electrically conductive substrate and a photoconductive element on the electrically conductive substrate, the photoconductive element comprising: (a) a polymeric charge transport material having the formula where n is a distribution of integers between 1 and 100,000 with an average value of greater than one; Y comprises an aromatic group; XSUB1 /SUBand XSUB2/SUB, each independently, is a bond or a linking group; QSUB1 /SUBand QSUB2 /SUBare, each independently, O, S, or NR; and R, RSUB1/SUB, and RSUB2 /SUBcomprise, each independently, H, an alkyl group, an alkenyl group, an alkynyl group, an acyl group, a heterocyclic group, or an aromatic group; and (b) a charge generating compound. Corresponding electrophotographic apparatuses, imaging methods, and methods of preparing the polymeric charge transport material are described.
