Abstract: An improved backup roll for use in the heated fuser system of electrostatic copy machines wherein the fuser system employs a fuser roll couple comprised of a heated fuser roll in pressure contact with the backup roll. In construction, the backup roll includes an aluminum core member with a coating of polyurethane reinforced flourinated ethylene propylene on its surface. The coating has heat transfer characteristics similar to the copy sheets fed through the couple so as to withdraw heat from the heated fuser roll, along each zone where it may make direct contact with it, at substantially the same rate as the copy sheets withdraw heat. The coating also has a thickness whereby the heat transferred to each zone during contact with the fuser roll is quickly transferred to the aluminum core before that zone again contacts the fuser roll.
