a fuser device for an electrostatographic reproduction apparatus . the fuser device includes an externally heated fuser roller having a thick elastomeric cover . an external heater assembly is positioned in operative association with the fuser roller . the external heater assembly has a low mass , fast - acting heating element to transfer heat rapidly to and from the external surface of the elastomeric cover of the fuser roller . a pressure film belt assembly is also in operative association with the fuser roller , spaced from the external heater assembly . the pressure film belt assembly has a pressure applicator which maximizes thermal contact and mechanical energy to define an optimum nip pressure profile providing an extended fusing nip with the fuser roller , thereby yielding quick starting , with superior energy efficiency and exceptional temperature control for the fuser device that provides proper image quality for photos , text , and graphics for high quality reproductions with consistent gloss .
