Organophotoreceptor with a charge transport material having two 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 R₁, R₂, R₃, R₄, R₅, R₆, R₇, and R₈ are, each independently, an alkyl group, an alkaryl group, an aryl group, or heterocyclic group, X and X' are, each independently, aromatic groups, and Z is a divalent linking group; and (b) a charge generating compound. Corresponding electrophotographic apparatuses and imaging methods are described.
