Abstract
A fixing device of the present invention supports rotatably a fixing belt heated by a heating member using a separation roller having hollow pipes arranged between a core roller and an outer peripheral roller and producing a high heat insulating effect though it is light in weight and inexpensive and prevents the fixing belt from falling in temperature due to the separation roller.
