PROBLEM TO BE SOLVED: To eject a sheet at a speed without any trouble in loading, regardless of the carrying speed of the sheet when it passes through a fixing means by providing a holding means for keeping the sheet between the fixing means and an ejecting means. SOLUTION: When an image is formed on an OHP sheet 12, the position of a flapper 13 is switched and the sheet 12 is guided to a reverse path 14 as the holding means having guides 14a and 14b and further, carried by a first carrying roller 15. The carrying speed V1 (second carrying speed) at this time is slower than a normal carrying speed V (first carrying speed), to attain fixation on the sheet 12. For instance, the carrying speed V1 is set 25mm/s with respect to the fact that the normal carrying speed V is 100mm/s. But, these values are different according to the outside diameter, material quality, etc., of the roller of a fixing unit. A backward feeding preventing flapper 17 is added to change the switching of the flapper 13 and the control of the drive of the first and second carrying rollers 15 and 16, etc. |
