Abstract:
A fixing apparatus comprising: a fixing member for fixing a toner image onto a recording material; a pressure member for pressing the fixing member to form a nip portion by which the recording material is nipped and conveyed; an external heating mechanism including an external heating belt for heating the fixing member by contacting an outer surface thereof; a retraction mechanism configured to retract the external heating mechanism from the fixing member; and a restricting portion for restricting the external heating belt so that the external heating belt is separated from the fixing member when the external heating mechanism is retracted from the fixing member by the retraction mechanism.
