Patent ID: 8532530

Claim:
A fixing device for fixing on a recording material a toner image formed on the recording material, said fixing device comprising: a fixing roller; a heating member configured to heat said fixing roller in contact with an outer surface of said fixing roller; and a pressing member configured to form a fixing nip between itself and said 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, and wherein 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 said heating member and said fixing roller, a drawing force F 1 for drawing the recording material, toward an upstream side of said fixing device with respect to a rotational direction of said fixing roller, nipped in the fixing nip between said fixing roller in a rest state and said pressing member and a drawing force F 2 for drawing the recording material, toward the upstream side with respect to the rotational direction of said fixing roller, nipped between said fixing roller in the rest state and said heating member are set so that the drawing force F 2 is not more than the drawing force F 1 so as to prevent said fixing roller from being tightened by the recording material.
