Organophotoreceptor with a charge transport material having at least three linked hydrazone groups

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 n is an integer between 3 and 6; R₁ and R₂ are, each independently, H, an alkyl group, an alkenyl group, an aromatic group, or a heterocyclic group; R₃, R₄, and R₅ are, each independently, H, thiol, hydroxyl, carboxyl, an amino group, a halogen, nitro, cyano, an alkyl group, an alkenyl group, an aromatic group, a heterocyclic group, or a part of a ring group; X₁ and X₂ are, each independently, a linking group; Y comprises an arylamine group; and Z is a bridging group; and (b) a charge generating compound. Corresponding electrophotographic apparatuses and imaging methods are described.
