Zusammenfassung:A fixing device includes an endless belt, a nip formation pad disposed inside a loop formed by the endless belt, and a radiant heater to heat the endless belt. A contact heater is disposed at least at one lateral end of the nip formation pad in a longitudinal direction of the nip formation pad. The contact heater includes a heat generator to heat at least one lateral end of the endless belt in an axial direction of the endless belt. A thermal conduction aid, covering a nip-side face of the nip formation pad and a nip-side face of the contact heater, conducts heat applied to the endless belt in the axial direction of the endless belt. The thermal conduction aid includes a heater-side face being disposed opposite the contact heater and covering at least the heat generator of the contact heater.
