A fixing device includes an endless belt, a fixing rotating body that fixes, in cooperation with the belt, a toner image formed on a recording medium nipped between the fixing rotating body and the belt while rotating in contact with the belt, a support member that supports a load with which the fixing rotating body nips the recording medium with the belt so as to form a nip portion to nip the recording medium between the belt and the fixing rotating body, a driving unit that circulates the belt in a state in which the fixing rotating body is separate from the belt, and a wind-on rotating body on which the belt is wound at a position adjacent to the support member on an upstream side in a direction of transport of the recording medium to the nip portion.
