PROBLEM TO BE SOLVED: To reduce a load, and lower noise by adsorbing the difference in recording paper carrying speed between an image forming device main body and a recording paper housing device when each image is formed on both the sides of the paper, by means of a double surface unit between the image forming device main body and the recording paper housing device. SOLUTION: In a process when the recording paper P is carried from an image forming device main body A to a double surface unit B, and when it is also carried from the double surface unit B to a recording paper housing device C, when the recording paper P is sensed by a recording paper delivery sensor 44 provided for a fixing unit 7 of the image forming device main body A, the recording paper carrying speed by a double surface carrying motor is controlled based on a command to be outputted to a double surface control part 27 in such a way that the recording paper carrying speed at the double surface unit B side coincides with the recording paper carrying speed at the recording paper housing device C side. |
