Abstract
A rapid warm-up fuser belt (and fusers and marking machines that use such a fuser belt) comprised of a conductive substrate having a resistive heating layer on one side and a release layer on the other side. The fuser belt further enables an electrical contact to the conductive substrate. Electrical current passing through the conductive substrate and through the resistive heating layer, causes the resistive heating layer to heat. The fuser belt can either provide for a direct electrical connection to the resistive heating layer, or it can include a semiconductive layer on the resistive heating layer that improves the electrical connection to the resistive heating layer.
