Abstract
Photoconductors comprise a substrate, a charge transport layer, and a charge generation layer. The charge transport layer comprises binder and a charge transport compound comprising at least one of a hydrazone, aromatic amine, or substituted aromatic amine, and the charge generation layer comprises binder, a phthalocyanine charge generating compound and a hindered hydroxylated aromatic compound. The hindered hydroxylated aromatic compound reduces electrical fatigue upon cycling without adversely effecting the electrical performance of the photoconductors.
