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 formulawhere Y comprises an aromatic group;X is a —(CH2)n— group, where n is an integer between 1 and 10, inclusive, and one or more of the methylene groups is optionally replaced by another atom or group;Q1, Q2, and Q3are, each independently, O, S, or NR; andR, R1, R2, and R3comprise, each independently, H, an alkyl group, an alkenyl group, an alkynyl group, an amino group, an acyl group, an alkoxy group, an alkylsulfanyl group, an aromatic group, or a heterocyclic group; and(b) a charge generating compound.Corresponding electrophotographic apparatuses and imaging methods are described.
