FIXING DEVICE

摘要

Disclosed is a fixing device (5) wherein a pressure belt (52) is rotated independently of a heating roller (51) in the paper delivery direction by second driving means (G) including an one-way clutch (F) which allows racing thereof in the paper delivery direction. The pressure belt (52) is rotated at a peripheral speed less than that of the heating roller (51) by the second driving means (G). The fixing device (5) can surely perform fixation without causing defective delivery or crumple regardless of papers or plastic films.
