Organic electrophotographic photoconductor with good sensitivity and fatigue resistance

摘要

Electrophotographic photoconductor has a conductive substrate and a photosensitive film with hole transport agent including hydrazone compound(s), comprising diphenylamine-4,4'-bis(aldehyde phenylhydrazone) with N-alkenyl substituent(s) of formula (I), and diamine(s), comprising 4,4'-bis(indolin-1-yl)-diphenyl of formula (II); in which one of R1, R2 = alkenyl and the other = optionally substituted alk(en)yl, ar(alk)yl or heterocyclyl; R3, R4 = hydrogen (H), halogen, alkyl or alkoxy; R5, R6, R7 = H, halogen, alkoxy or optionally substituted alkyl or aryl.
