Abstract
A fixing device fixes on a recording material a toner image formed on the recording material and includes a fixing roller, a heating member for heating the fixing roller in contact with an outer surface of the fixing roller, and a pressing member for forming a fixing nip between itself and the fixing roller. When the recording material which has been jammed so that its leading end passes through the fixing nip to reach a contact portion between the heating member and the fixing roller, a force for drawing the recording material upstream when nipped in the fixing nip is at least equal to the drawing force of 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.
