ABSTRACT:
A photoconductor for use in electrophotographic reproduction devices is disclosed. This photoconductor exhibits reduced room light and cycling fatigue without any corresponding negative impact on the sensitivity of the photoconductor. The photoconductor of the present invention includes specifically defined fluorenyl-azine derivatives in its charge transport layer. These materials have the formula: ##STR1## wherein R.sub.1 and R.sub.2 independently selected from C.sub.1 -C.sub.4 alkyl and phenyl, and R.sub.3 is selected from hydrogen, C.sub.1 -C.sub.4 alkyl, and phenyl.
