Abstract
A fixing device includes: a plurality of heating units which individually heat a plurality of areas of a fixing member; an acquisition unit which acquires information on an image forming range and a non-image forming range of the recording sheet for each of the plurality of divided heating areas; and a control unit which performs first control for controlling the corresponding heating unit such that a contact portion of the image forming range of the recording sheet has a target fixing temperature when the image forming range contacts the fixing member at the contact portion of the image forming range, and second control for controlling the corresponding heating unit such that a contact portion of the non-image forming range of the recording sheet has a temperature lower than the fixing temperature when the non-image forming range contacts the fixing member at the contact portion of the non-image forming range.
