Abstract
PURPOSE: To stably convey an image carrier and perform good fixing by cooling or heating one end of the fixing roller so that the temperature differnces of its both ends become of a specified range.
CONSTITUTION: While copying paper 20 is being conveyed by a fixing roller 31 containing a heater 35 in its hollow part and a backup roller 32 turning in contact therewith, the toner images formed on the copying paper 20 are heat fixed. One end of this roller 31 is controlled by cooling with a fan 44 so that its temperature has a difference of the specified range as compared to the temperature of the other end. As a result, the oblique conveying, zigzag conveying, etc. of the copying paper owing to the temperature differences of both ends of the roller 31 are prevented, the copying paper stably conveyed and the toner well fixed. The similar results are also obtained even by heating one end of the fixing roll whose temperature becomes lower than that of the other end.
