Abstract:
In a fixing device for fixing a toner image on a recording medium, a fixing roller and a heating roller support a fixing belt. A pressing roller presses against the fixing roller via the fixing belt to form a fixing nip between the fixing belt and the pressing roller. A tension roller presses against the fixing belt to apply tension to the fixing belt. A primary heat source heats the fixing belt, and is disposed along an outer face of the fixing belt opposite the heating roller. A secondary heat source is provided inside the tension roller to supply deficient heat not provided by the primary heat source.
