<p>An image forming apparatus comprising: an electronic photography process mechanism for transferring an image, as developed in an image forming unit, primarily to an intermediate transfer belt and then transferring the transferred image secondarily to a sheet of paper; a detector for detecting a change in the belt length from the motion of a tension roller disposed at the intermediate transfer belt; and a timing regulating unit for vegulating the control timing of the electronic photography process mechanism on the basis of the change in the belt length by the detector. The image forming apparatus detects the change in the belt length in real time and keeps the precision for each sheet of paper with respect to the change in the belt length.</p> |
