Abstract
A heated fuser roller that includes an elongated roller and a series of heating wires extending axially through the roller. The heating wires are positioned near the surface of the roller. Voltage is applied from a power source to the heating wires through conductive disks mounted on each end of the roller. A conductive wiper, shoe or other suitable contact device slides along each disk to maintain the electrical connection between the disks and the power source as the roller rotates.
