Abstract
A fixing device includes first and second rotatable members, a heating portion, a detecting portion configured to detect a temperature of the first rotatable member, a controller configured to control supplied electrical power to the heating portion depending on the detected temperature, and a setting portion configured to set a nip pressure at a first pressure when a recording material of a first kind is subjected to a fixing process and configured to set the nip pressure at a second pressure less than the first pressure when a recording material of a second kind is subjected to the fixing process. The controller controls the supplied electrical power depending on a difference between a target temperature of the first rotatable member and the detected temperature. The supplied electrical power is less when the nip pressure is the second pressure than when the nip pressure is the first pressure.
