A fixing device includes a rotary heating member; a heat source disposed near the rotary heating member to heat the rotary heating member; a stationary member disposed in sliding contact with a portion of an outer circumferential surface of the rotary heating member; a flexible fixing belt looped around the rotary heating member and the stationary member; and a rotary pressure member disposed in pressure contact with the stationary member via the fixing belt to form a nip between the fixing belt and the rotary pressure member. The rotary heating member, the stationary member, the fixing belt, and the rotary pressure member are arranged in a direction in which pressure is applied to form the nip. A pressing force acting between the rotary heating member and the rotary pressure member via the fixing belt and the stationary member creates pressure at the nip.
