Abstract: A fixing device includes: a heat source, a heating member, a pressure member, a heat absorption unit, a holding member, and an end part supporting member. The heat source generates infrared rays. The heat absorption unit is formed on an inner circumferential surface of the heating member, absorbs radiation heat of the heat source, and opposes an outer circumferential part of the holding member with a gap. The holding member has a hollow and cylindrical shape, and arranged between the heat source and the inner circumferential surface of the heat member, permits transmission of infrared rays and has heat resistance. The end part supporting member supports the holding member at both axial end parts of the heating member. The outer circumferential part of the holding member, the inner circumferential surface of the heating member, and the end part supporting member form a sealing space sealing the heat absorption unit.
