Abstract
A fixing device for fixing an image formed on a recording material in an image forming apparatus includes a fixing member configured to fix an image formed on the recording material, 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 storage unit so as not to supply power to the heating part during a warming-up period from when a power switch of the image forming apparatus switches on to when the image forming apparatus becomes ready to start an image forming operation and that controls the external power source and the storage unit to supply power to the heating part during a returning period from when an off-mode is completed to when the image forming apparatus becomes ready to start the image forming operation.
