Abstract
A fixing device includes a belt, an opposed rotator, a nip formation pad, a heater, a stay, and a positioner. The nip formation pad has a plurality of projections in a longitudinal direction of the nip formation pad. The positioner is disposed between the nip formation pad and the stay to position the nip formation pad. The positioner has a plurality of insertion holes arranged in a longitudinal direction of the positioner to accept the projections and restrict movement of the nip formation pad with respect to the positioner in a rotation direction of the belt and a direction opposite the rotation direction. The plurality of insertion holes includes an insertion hole disposed at a position corresponding to an end portion of the nip formation pad to accept two or more projections of the projections arranged in the longitudinal direction of the nip formation pad.
