摘要： A fixing device includes an endless belt rotatable in a predetermined direction of rotation and an opposed rotator contacting an outer circumferential surface of the endless belt. A nip formation pad, disposed opposite an inner circumferential surface of the endless belt, presses against the opposed rotator via the endless belt to form a fixing nip between the endless belt and the opposed rotator, through which a recording medium is conveyed. A belt holder contacts and rotatably supports a lateral end of the endless belt in an axial direction thereof. A ring is interposed between the belt holder and a lateral edge face of the endless belt. A restraint disposed opposite the ring contacts the ring to restrict movement of the ring in a radial direction of the endless belt within a trajectory of the lateral end of the rotating endless belt.
