ABSTRACT:
A fixing device for fixing an image formed on a recording material includes a fixing member disposed on a recording material conveyance path, a heating part that heats the fixing member to fix the image formed on the recording material by heat, and a storage unit that is charged by an external power source to supply power to the heating part. The fixing device further includes a fixing temperature detecting unit that detects a temperature of the fixing member, and a control unit that controls the external power source to supply power to the heating part and to determine whether to start to supply power to the heating part from the storage unit based on the temperature of the fixing member, at the time of warming-up the fixing member by the heating part.
