Abstract

PURPOSE: To stably convey an image carrier and form good images by detecting the displacement of the image carrier being conveyed by a fixing device and controlling the temperature differences of both side ends of the fixing roller, etc. as to become within a fixed range.
CONSTITUTION: The displacement of the image carrier for copying paper, etc. having been fixed and being conveyed by the heat fixing device constituted by a backup roller, fixing roller, etc., in the direction at a right angle to the conveying direction of said carrier is detected with a photoelectric transudcer 483 and is compared with the reference voltage having been set in a constant voltage circuit 7-2 in a comparator 7-3. If according to this compared value the fans 46, 57 cooling the both end parts of the fixing roller, etc. are controlled b8 driving circuits 7-5, 7-6, the temperature differences at both end parts of the fixing roller, etc. become within the specified range and the oblique and crooked running, etc. of the image carrier owing to temperature differences may be prevented. Hence, the image carrier is fixed and stably conveyed, whereby good quality images are formed. The similar results are also obtained even by performing temperature controlling according to the detected temperatures at both end parts of the fixing roll, etc. corresponding to the displacement of the image carrier.
