摘要： A fixing device includes a rotator, a heat source to heat the rotator, a first thermal equalization plate, a second thermal equalization plate, and an overheating preventer. The first thermal equalization plate and the second equalization plate are in contact with the heat source. The overheating preventer is in contact with one end of the second thermal equalization plate in an axial direction of the rotator. The first thermal equalization plate is in contact with a portion of the heat source, and the portion of the heat source is farther from a center of the rotator than the one end of the second thermal equalization plate in the axial direction of the rotator. The first thermal equalization plate is spaced apart from the one end of the second thermal equalization plate.
