Abstract
Toner images of different colors are superimposed on a transfer belt of an endless type from image carriers, to form a full color toner image. A tension roller maintains a tension of the transfer belt. A driving roller drives the transfer belt. A biasing unit applies the tension to the tension roller. A holding unit holds the tension roller. An image reading sensor detects the toner image formed on the transfer belt. The image reading sensor is disposed in the holding unit, in an opposite position to the tension roller with respect to the transfer belt.
