Abstract
This invention relates to an organophotoreceptor that includes:(a) a charge transport compound having the formula  where R1 and R2 are, independently, a carbazolyl group;R3 and R4 are, independently, hydrogen, an alkyl group, an aryl group, or a heterocyclic group; andX is a sulfonyldiphenylene group;(b) a charge generating compound; and(c) an electrically conductive substrate.
