ABSTRACT:
A heating section (1) heats a fixing roller (10). A cooling section (2) cools the interior of a unit or apparatus. A temperature detecting section (3) detects the temperature of the fixing roller (10). A control section (4) controls current conduction to the heating section (1) based on the detected temperature. A conduction cutoff section (5) cuts off current conduction to the heating and cooling sections (1, 2) regardless of conduction control by the control section (4) if the detected temperature exceeds a predetermined temperature.
