This disclosure relates to a belt fuser wherein a belt 25 is entrained about a pair of rolls 26 and 27, one of which is provided with means for driving it, The belt cooperates with a backup roller 28 to form a nip through which copy substrates S having toner images thereon pass with the images contacting the belt. A heater 30, disposed in the loop formed by the belt, serves to elevate the temperature of the belt suf-ficiently to tackify the toner images to effect the fusing process. In order to minimize paper wrinkle, the belt has a tapered configuration whereby the portions of the belt near the edges are thicker than the center-most part of the belt.
