Abstract:
1. A fixing device for fixing an image formed on a recording material, comprising: a fixing member; a heating part configured to heat the fixing member; a pressing member configured to press-contact the fixing member, the fixing member and the pressing member being rotatable to pass the recording material having an image through a nip part formed between the fixing member and the pressing member, to thereby fix the image onto the recording material by heat and pressure; a storage unit configured to be charged by an external power source to supply power to the heating part; and a control unit configured to control the external power source to supply power to the heating part, to determine whether to start to supply power to the heating part from the storage unit, and to select one of a first case and a second case at a time of warming-up the fixing member by the heating part, wherein the control unit is configured to control the external power source and the storage unit to supply power to the heating part without rotating the fixing member and the pressing member in the first case, and the control unit is configured to control the external power source to supply power to the heating part and to control the storage unit so as not to supply power to the heating part while rotating the fixing member and the pressing member in the second case.
