Abstract
A fixing device includes a fixing rotator, a heat conductor, a pressure rotator, a heater, a pressure-receiving portion, and a heat insulator. The heat conductor contacts an inner circumferential surface of the fixing rotator to uniform temperature distribution in a rotation axis direction of the fixing rotator. The pressure rotator presses the fixing rotator against the heat conductor to form a nip and presses a recording medium passing through the nip. The heater is disposed inside a loop of the fixing rotator. The pressure-receiving portion contacts the heat conductor to receive pressure from the pressure rotator via the fixing rotator. The heat insulator is between the pressure-receiving portion and the heat conductor and includes a sheet-shaped silica aerogel.
