Abstract
A fixing device includes a fixing rotator, a pressure rotator, a heater inside the fixing rotator, a reflector, and a sliding member. The pressure rotator is in contact with the fixing rotator to form a nip and presses a recording medium passing through the nip. The reflector includes a reflecting portion that reflects radiant heat radiated by the heater toward an inner circumferential surface of the fixing rotator and a pressure receiving portion that receives a pressing force of the pressure rotator via the fixing rotator. The pressure receiving portion is thermally coupled to the reflecting portion. The sliding member is between the pressure receiving portion and the fixing rotator and in contact with the pressure receiving portion and the fixing rotator. With respect to the inner circumferential surface of the fixing rotator, the sliding member has a smaller friction coefficient than a surface of the pressure receiving portion.
