Abstract
A heat and pressure roller-type fusing apparatus for fusing toner images onto a substrate includes a fuser roller which has a hollow metallic core and at least an elastomeric outer layer that is formed over the core. A heat source is mounted within the metallic core for heating such core and the elastomeric layer to a desirable fusing temperature. The fuser roller includes a first length portion which is substantially equal to the cross-track dimension of the substrate for contacting the substrate, and a second length portion which adjoins the first length portion and an end of the fuser roller. The fuser roller also includes a heat absorbing and dissipating member that is mounted inside the hollow core for inwardly absorbing and dissipating heat from the core within the second length portion of the fuser roller, thereby reducing the heating and temperature of the surface of such second length portion of the fuser roller.
