Improved organophotoreceptor comprises an electrically conductive substrate and a photoconductive element on the electrically conductive substrate, the photoconductive element comprising: (c) a charge transport material having the formula: <?in-line-formulae description="In-line Formulae" end="lead"?>R<SUB>1</SUB>-N-N-Ar<SUB>1</SUB>-X-Ar<SUB>2</SUB>-N-N-R<SUB>2 </SUB><?in-line-formulae description="In-line Formulae" end="tail"?> where R<SUB>1 </SUB>and R<SUB>2 </SUB>comprise, each independently, a 4-oxo-2,5-cyclohexadiene-1-ylidenyl group; X comprises oxy, thio, sulfonyl, sulfinyl, sulfonyldioxy, azo, carbonyl, thiocarbonyl, carbonyldioxy, oxalyl, an arylene group, an arylenebisazo group, an imino group, a hydrazo group, a carbonimidoyl group, a vinylene group, or a combination thereof; and Ar<SUB>1 </SUB>and Ar<SUB>2 </SUB>comprise, each independently, an aromatic group; and (b) a charge generating compound. Corresponding electrophotographic apparatuses, imaging methods, and the charge transport material are also described.
