Abstract
PURPOSE:To improve the thermal stability of paired rollers while reducing electric power consumption and noise by cooperatively rotating the paired rollers in an initial stage when heating is shifted to a normal set temp. CONSTITUTION:The cooperative rotation and rotation stop of the paired rollers 20, 21 are repeated at every prescribed time while the energization of a heating means is controlled in the state when the thermal fixing roller 20 shifts to the normal set temp. after the end of warming up or warming down of the fixing roller 20, by which the normal set temp. is maintained. Namely, the electrical power consumption is reduced and the overall noise is reduced by intermittently and repeatedly rotating the paired rollers 20, 21 at every prescribed time cycle without continuously rotating the rollers 20, 21.
