An externally heated fuser roller to achieve good fusing performance, long life and relatively quick warm-up time. The fuser roller is made up of a metal core, an insulation elastic layer, a heat transport layer and optionally a release layer such that the thickness of the heat transport layer is in the range of about 0.25 and about 1 mm, the effusivity value of the heat transport layer be equal to or greater than about 800 W√s(m2K), the total thermal capacity of the heat transport layer is less than about 200 J/m K, and the effusivity value of the insulation elastic layer is less than about 400 W√s(m2K). |
