Abstract
A rapid warm-up fuser roller (and fusers and marking machines that use such a fuser) comprised of a metallic cylindrical core, a thermally and electrically insulating layer of volume graft over the metallic core, a resistive heating layer over the insulating layer, and electrical connections to the resistive heating layer such that electrical current passing through the electrical connections flows through the resistive heating layer in a direction that is substantially parallel to the axis of the metallic core. The electrical current causes the resistive heating layer to heat while the insulating layer of volume graft enables rapid warm-up of the roller.
