Abstract

PURPOSE:To prevent the deformation due to temperature distribution and heat to obtain a heat roller fixing device f a high fixing performance, by constituting a metallic roller of the heat roller fixing device with plural cylindrical layers. CONSTITUTION:A heat roller 1 is a metallic cylindrical roller and is constituted by superposing an iron metallic roller 3 superior in creep resistance on an aluminium metallic roller 2 of a high heat conductivity in concentric cylindrical layers, and a heating unit 4 is incorporated in the center. Just after copies of the size of B6 are continuously fixed by this heat roller fixing device, the temperature distribution is uniform and good and is restored to a uniform temperature distribution in a speed twice or more as high as the speed for the use of a heat roller consisting of only iron. This heat roller is not deformed even if it is always put in the press state, and a good fixing performance is obtained.
