Abstract
A photoconductor for use in electrophotographic reproduction devices is disclosed. The photoconductor provides simultaneous improvement in both photoreceptor sensitivity and fatigue, while also providing higher charge voltage, lower residual voltage and lower dark decay. The photoconductor of the present invention includes simple quinone additives in either the charge generation layer, the charge transport layer, or both layers. Quinone additives are preferably selected from o-quinone, duroquinone, diphenoquinone, naphthaquinone, and mixtures of those materials, with duroquinone and the mixture E+Z 3, 3'-di-t-butyl-5, 5'-dimethyl diphenoquinones being preferred.
