Abstract
Provided is an imaging member such as photoreceptor comprising a substrate, a charge generation layer, a first charge transport layer, a second charge transport layer, and an optional overcoat layer. The first charge transport layer is formed from a first CTL formulation comprising an aromatic monoamine and a first polymeric film forming binder material. The second charge transport layer is formed from a second CTL formulation comprising aromatic diamine and a second polymeric film forming binder material. The imaging member has gained improved properties such as removal of anti-curl layer, desirable structural flatness, electrical properties, mechanical robustness, flexibility, longevity, and copy image qualities over extended use, among others.
