Abstract
An image forming apparatus includes a voltage applying unit to apply a voltage to and charge a surface of transport belt, a leak judging unit to judge a charge leak on the surface of the transport belt, and a recovery operation unit to perform a charge leak recovery operation in which the transport belt is driven in a state where the voltage applying unit applies no voltage to the transport belt, if the leak judging unit judges that the charge leak is generated on the surface of the transport belt. The leak judging unit again judges whether the charge leak is generated on the surface of the transport belt after the recovery operation unit performs the charge leak recovery operation.
