BISAZO-BASED CHARGE TRANSPORT MATERIALS HAVING 4-OXO-2,5-CYCLOHEXADIENE-1-YLIDENE GROUPS, ELECTROPHOTORECEPTOR AND ELECTROPHOTOGRAPHIC IMAGING APPARATUS COMPRISING THE SAME, AND ELECTROPHOTOGRAPHIC IMAGING PROCESS USING THE SAME

摘要

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"?RSUB1/SUB-N-N-ArSUB1/SUB-X-ArSUB2/SUB-N-N-RSUB2 /SUB?in-line-formulae description="In-line Formulae" end="tail"? where RSUB1 /SUBand RSUB2 /SUBcomprise, 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 ArSUB1 /SUBand ArSUB2 /SUBcomprise, each independently, an aromatic group; and (b) a charge generating compound. Corresponding electrophotographic apparatuses, imaging methods, and the charge transport material are also described.
