Abstract
A fixing device includes an endless belt, a first radiant heater including a first heat generator to heat the endless belt, and a second radiant heater including a second heat generator, disposed outboard from the first heat generator in an axial direction of the endless belt, to heat the endless belt. A nip formation pad includes a nip-side face disposed opposite the endless belt. A contact heater heats at least one lateral end of the endless belt in the axial direction of the endless belt. The contact heater includes a nip-side face disposed opposite the endless belt. A thermal conduction aid covers the nip-side face of the nip formation pad and the nip-side face of the contact heater and conducts heat applied to the endless belt in the axial direction of the endless belt.
