Abstract
A fixing device for fixing an image formed on a recording material in an image forming apparatus includes a fixing member, a heating part that heats the fixing member to fix an image formed on the recording material by heat, 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 to supply power to the heating part and determines whether to start to supply power to the heating part from the storage unit. The control unit controls the external power source to charge the storage unit during a period from when power supply from the storage unit to the heating part is completed at the time of warming-up the fixing member by the heating part until when the power supply from the storage unit to the heating part is started.
