Abstract:
An image forming apparatus includes an image forming unit that forms a developer image on a recording medium using a developer, and a fixing unit that fixes the developer image to the recording medium. The fixing unit includes a heating member that heats the recording medium on which the developer image is formed, a plurality of pressure members that press the recording medium against the heating member, and a fixing belt stretched around the plurality of pressure members and nipped between the heating member and the plurality of pressure members so as to form a plurality of nip portions. Each of the plurality of pressure members has a shape in which a center portion protrudes more outward than both end portions.
