Abstract
A fixing member, a power detector, and a controller are included. The fixing member is heated by a heating unit that generates heat when power is supplied by a commercial power and a capacitor. The power detector detects energy of power stored in the capacitor. The controller performs an identical control to reduce number of copies of an image formed (fixed) per minute (CPM) to a predetermined number (40 CPM) in any of three cases in which the energy is less than a threshold for starting electric discharge when a plurality of recording mediums is continuously passed through the fixing member, in which a cardboard paper is continuously passed, and in which an amount of data of an image to be transferred on the recording medium is large.
