Abstract
A fixing roller cooperates with a pressing roller to heat and press a toner image to a recording medium so as to fix the toner image to the recording medium. A sheet-like web is impregnated with a mold release for supplying the mold release to a surface of the fixing roller by being pressed by the pressing roller. A first shaft has an unused portion of the web wound therearound, and a second shaft takes up the web after supplying the mold release to the fixing roller. A coil spring applies a rotational force in a direction opposite to a direction of drawing out the web relative to the first shaft so as to apply a tension to the web, thereby automatically removing slackness of the web.
