<p>PROBLEM TO BE SOLVED: To provide an image forming device capable of stopping the rotation of an inversion roller simultaneously with the gate passing time of a paper sheet trailing end. SOLUTION: The image forming device is provided with a guide gate 53 capable of freely coming into contact and uncontact corresponding to the inversion roller 51, parting from the inversion roller 51 as a result of the paper sheet carrying in, while coming into contact with the inversion roller 51 as the result of the paper sheet trailing end passing through, and guiding the paper sheet fed from the trailing end side by the inversion rotation of the inversion roller 51 to the second transporting means 45, a sensor 57 detecting the contact of the guide gate 53, when the guide gate 53 is held in contact with the inversion roller 51 by the paper sheet trailing end allowed to pass through, and a control part 58 letting the inversion roller 51 stop normal rotation and inversely rotate, when the sensor 57 detects the guide gate 53 brought into contact.</p> |
