Hydrazone-based charge transport materials

摘要

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 having the formula where R₁ and R₂ are, each independently, an alkyl group, an alkenyl group, an alkynyl group, an aromatic group, or a heterocyclic group; R₃ and R₄ are, each independently, H, an alkyl group, an alkenyl group, an alkynyl group, an aromatic group, or a heterocyclic group; X₁ and X₂ are, each independently, a linking group; Y₁ and Y₂, each independently, comprise an arylamino group; and Z is a bridging group; and (b) a charge generating compound. Corresponding electrophotographic apparatuses and imaging methods are described.
