Charge transport materials having heteroaromatic hydrazone groups

摘要

An improved organophotoreceptor includes an electrically conductive substrate and a photoconductive element on the electrically conductive substrate where the photoconductive element comprises: a) a charge transport material having the following formula: where X is a linking group; Y₁ and Y₂ are, each independently, a phenothiazine group, a phenoxazine group, or a phenazine group; R₁, R₂, R₃, and R₄ are, each independently, an alkyl group, an alkenyl group, a heterocyclic group, or an aromatic group; and R₅ and R₆ are, each independently, a hydrogen, an alkyl group, an alkenyl group, a heterocyclic group, or an aromatic group; and (b) a charge generating compound. Corresponding electrophotographic apparatuses and imaging methods are described.
