Abstract
A fixing device includes a first heat generator and a second heat generator that heat a fixing rotator. A support is disposed inside the fixing rotator. A reflector is mounted on the support and interposed between the support and each of the first heat generator and the second heat generator to reflect light radiated from the first heat generator and the second heat generator toward the fixing rotator. The reflector includes a body mounted on the support and a shield portion projecting from the body toward the first heat generator and the second heat generator to shield the fixing rotator from the first heat generator and the second heat generator. The shield portion includes a wing disposed opposite a non-conveyance span of the fixing rotator in the axial direction thereof where a recording medium is not conveyed over the fixing rotator.
