Abstract:
In an image forming apparatus, in which a belt driving device, provided in an image forming part, has: plural rollers including a driving roller; an endless belt; a driver, with one roller as a tension control roller to control tension applied to the endless belt, that moves the tension control roller in a vertical direction to an axis of another roller; a position detector that detects the position of the tension control roller; a pressure detector that detects pressure added with the endless belt to the tension control roller; and a controller that controls movement of the tension control roller. To set the tension applied to the endless belt as a predetermined value, the controller controls the driver to bring the detected pressure closer to a target pressure to be added to the tension control roller in the detected position of the tension control roller.

Claim (Index 9):
A method of controlling a belt driving device comprising: a plurality of rollers including a driving roller; an endless belt stretched around the plurality of rollers; and a driver, with one of the plurality of rollers as a tension control roller to control tension applied to the endless belt, that moves a position of the tension control roller in a vertical direction to an axis of another roller, comprising:\n detecting the position of the tension control roller with a position detector; detecting pressure applied from the endless belt to the tension control roller with the pressure detector; and controlling, to set the tension applied to the endless belt as a predetermined value, the driver to bring the pressure detected with the pressure detector closer to a target pressure to be added to the tension control roller in the position of the tension control roller detected with the position detector, with the controller.
