A fixing device includes a pressurizer constituted of a rotating body, and a heater including a heat source, a fixing belt heated by the heat source, and a pressing portion disposed inside the fixing belt sandwiched between the pressing portion and the pressurizer disposed outside the fixing belt. The fixing device further includes a non-contact type temperature detector for measuring surface temperature of the fixing belt, a displacement detector for detecting a displacement of a measurement target position of the fixing belt with respect to the temperature detector, and a controller configured to adjust amount of heat generation of the heat source on the basis of the temperature detected by the temperature detector and the displacement detected by the displacement detector, so as to perform temperature adjustment of the surface temperature of the fixing belt. |
