Abstract
A belt unit dismountably mounted on a main assembly includes an endless belt, a tension mechanism, a tension releasing member and contacting portion. The tension mechanism includes a tension roller applying the tension to the belt by stretching the belt and movably provided between a first position where the tension is applied to the belt and a second position where the tension is released and an urging member urging the tension roller. The tension releasing member restricts movement of the tension roller from the second position to the first position and permits the movement by engagement with the tension mechanism being released. The contacting portion provided on the tension releasing member prevents the belt unit from being mounted on the main assembly when the belt unit is to be mounted in a state in which the tension releasing member is engaged with the tension mechanism.
