ABSTRACT:
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 E comprises a functional group selected from the group consisting of a reactive ring group, an ethylenically unsaturated group, a hydrazone group, and an azine group;R1, R2, and R3comprise, each independently, H or an organic group;X is a bond or a linking group, with the proviso that when E comprises a reactive ring group, X is a linking group; andY is a nitrogen-containing aromatic heterocyclic group; and(b) a charge generating compound.
