摘要：
A fixing device for fixing an image formed on a recording material includes first and second rotary members having a nip part therebetween, a heating part that heats the first rotary member, a center portion temperature detecting unit that detects a temperature of a center portion of the first rotary member, and an end portion temperature detecting unit that detects a temperature of an end portion of the first rotary member. When recording materials each having a relatively large width consecutively pass through the nip part, a control unit controls a heating amount of a full width heating member based on the temperature detected by the center portion temperature detecting unit, and when recording materials each having a relatively small width consecutively pass through the nip part, the control unit controls the heating amount of the full width heating member based on the temperature detected by the end portion temperature detecting unit.
