Abstract
A fixing device for an image forming apparatus of the present invention includes an endless belt passed over a plurality of members for conveying a sheet in contact with a toner image carried thereon. A pressing member faces the above members with the intermediary of the belt. A first member, which is one of the plurality of members, constitutes a heating member for heating the belt. A second member, which is another one of the members, faces the pressing member with the intermediary of the belt. A third member, which is another one of the members, constitutes a stationary member facing the pressing member with the intermediary of the belt. The pressing member and first member and the pressing member and second member respectively form a first and a second nip therebetween. The toner image on the sheet is fixed by being sequentially conveyed via the first and second nips.
