<P>PROBLEM TO BE SOLVED: To provide an image forming device which equalizes the wear state of the circumferential face of a tension granting roller. <P>SOLUTION: A control part performs the processing which makes a backward-movement by 10 inches, i.e., 254 mm when the next picture output does not exist after the image formation of the image output forming the image of one or a plurality of sheets is finished. Considering that the processing of backward-movement by 1/6 inch, i.e., 4.23 mm is performed when an indication of backward-movement is given by a manual operation, the tension granting roller 13 with the circumferential face avoiding the integral multiple and one time for integer of 254 mm and 4.23 mm is manufactured. <P>COPYRIGHT: (C)2010,JPO&INPIT |
