Abstract
A fixing device includes: an endless belt; a heater; a stay; a holder having a heater supporting surface and a contacting surface in contact with the stay; and a pressure roller having a diameter that becomes smaller from each end of the pressure roller in an axial direction toward a center of the pressure roller in the axial direction. In a state prior to assembling the holder with both the stay and the heater, a distance in an orthogonal direction between the heater supporting surface and the contacting surface at a center of the holder in the axial direction is longer than a distance in the orthogonal direction between the heater supporting surface and the contacting surface at each end of the holder in the axial direction. The orthogonal direction is orthogonal to the axial direction.
