Abstract
A fixing device for fixing an image formed on a recording material includes a fixing member and a pressing member which are rotatable to pass the recording material having an image through their nip part, a heating part that heats the fixing member, a storage unit that is charged by an external power source to supply power to the heating part, and a control unit that controls the external power source and the storage unit to supply power to the heating part without rotating the fixing member and pressing member at a time of warming-up the fixing member by the heating part in a first case. The control unit further controls the external power source to supply power to the heating part and controls the storage unit so as not to supply power to the heating part while rotating the fixing member and the pressing member in a second case.
