  • Publication number: 20080026309
    Abstract: An imaging belt comprises a substrate layer, an outer image layer and an inner anti-curl backing layer. The inner anti-curl backing layer, in turn, includes one or more carbon nanotubes disposed therein, together with an exposed backing layer surface. An image forming device includes the imaging belt. The image forming device is arranged to conductively couple the backing layer surface to an included ground source by means of one or more included conducting backer bars, one or more included grounding brushes, or any combination of included conducting backer bars and grounding brushes.
