Abstract
Printing machines which incorporate a transfusing station having a transfusing member with a resistive heater layer, a substrate, and a release layer. The transfusing station is entrained between at least two electrically conductive contact members, such as rollers, which electrically contact the heater layer. An electrical source sends current through the conductive rollers and the heater layer, heating that layer, the substrate, the release layer, and any toner on the release layer. A backup roller adjacent the transfusing member and the conductive rollers induces pressure on marking substrates which pass between the backup roller and the transfusing member. The combination of heat from the heater layer and pressure induced by the backup roller causes any toner image on the transfusing member to fuse onto the marking substrate. The release layer assists in transferring the toner onto the marking substrate.
