Abstract
A fixing apparatus includes a first heat generating member that generates heat upon receiving power from a commercial power source, an electrical condenser that stores charge when charged by the commercial power source, and a second heat generating member that generates heat upon receiving power from the electrical condenser. A fixing member is heated by the first and second heat generating members and fixes an image onto a recording medium. A control device is provided to restrict the power supplied from commercial power source to the first heat generating member when the temperature of the fixing member starts increasing. The electrical condenser starts supplying power to the second heat generating member before the control device terminates restriction of the power.
