PROBLEM TO BE SOLVED: To smoothly absorb the rotational vibration of a driving part to drive a fixing roller. SOLUTION: A helical gear is used as a gear intervening between a fixing driving motor 51 and the fixing roller 64. The contact ratio of the gear is raised by adopting the helical gear. Thus, vibration transmitting through a paper from a fixing device 6 and reaching an image forming part 5 is suppressed, and the pitch unevenness of a formed image is reduced.
