  • Patent number: 7070893
    Abstract: An electrographic or electrostatographic imaging member comprises a supporting substrate, an undercoating layer, a charge generating layer, and a charge transport layer. Thick undercoating layers were prepared with a charge erase enabler by doping an undercoating layer with a charge generating pigment that is strongly absorbing at typical erase lamp light. Doped thick undercoating layers demonstrate good electrical properties with an erase energy reduction of at least 50 V. A process for fabricating an imaging member and an apparatus comprising such an member are also disclosed.
