1 more element
An apparatus for heating a belt of a fusing device, comprising:
- a heating member including a heating element foamed on a planar heating surface;
- and
- a metal guide for transferring heat to the belt, the metal guide including a curved outer surface for contacting and tightly stretching the belt and a planar inner surface that is co-planar, and in contact, with the planar heating surface of the heating member to transfer heat from the heating member to the curved outer surface and thereby heat the belt.
