A pressure roller fuser includes a member at the end of at least one of the rollers for extending the position for applying the loading force between the rollers away from the center of the roller to cause the roller to bend with respect to the other roller. The bending causes a spreading of the nip at the edges of the roller to reduce wrinkling of the sheets fed through the nip. The amount of bend can be varied by varying the position of the loading force with respect to the center of the rollers, thereby allowing adjustment of the flare of the nip according to ambient conditions or the life of the rollers.
