Fixing device

Abstract

A fixing device for fixing on a recording material a toner image formed on the recording material includes a fixing roller; a heating member for heating the fixing roller in contact with a surface of the fixing roller; and a pressing member for forming a fixing nip between itself and the fixing roller, wherein the recording material on which the toner image is formed is subjected to fixing by being nipped and conveyed in the fixing nip. When the recording material which has been jammed is removed by pulling a trailing end of the recording material in a winding jam state in which a leading end of the recording material has passed through the fixing nip to reach a contact portion between the heating member and the fixing roller, a drawing force F1 for drawing the recording material, toward an upstream side with respect to a rotational direction of the fixing roller, nipped in the fixing nip between the fixing roller in rest state and the pressing member and a drawing force F2 for drawing the recording material, toward the upstream side with respect to the rotational direction of the fixing roller, nipped between the fixing roller in the rest state and the heating member are set so that the drawing force F2 is not more than the drawing force F1 so as to prevent the fixing roller from being tightened by the recording material.
