An image forming device includes: an image forming section, a fixing unit, an oscillation mechanism and a controller. The image forming section forms an image on paper. The fixing unit thermally fixes the image on the paper by using a fixing rotating member to pinch and convey the paper. The oscillation mechanism oscillates at least the entire fixing rotating member of the fixing unit in an axis direction thereof. The controller determines an oscillation quantity of the fixing rotating member based on rigidity of the paper in a state where the paper is pinched and conveyed by the fixing rotating member and another rotating member at the same time, and oscillates the fixing rotating member using the oscillation mechanism with the determined oscillation quantity. The controller determines the oscillation quantity of the fixing rotating member to be reduced as rigidity of the paper becomes lower.
An image forming device, comprising:
A control method of an image forming device which includes an image forming section to form an image on paper, a fixing unit to thermally fix the image on the paper by using a fixing rotating member to pinch and convey the paper on which the image has been formed by the image forming section, an oscillation mechanism to oscillate at least the entire fixing rotating member of the fixing unit in an axis direction thereof, and another rotating member to pinch and convey the paper, the another rotating member being provided on an upstream side or a downstream side of the fixing unit in a paper conveying direction, said control method comprising the steps of:
