Abstract
A printing apparatus is provided which can prevent foreign matters such as ink adhering to the surface of the conveying belt from getting transferred to other constitutional components. When the conveying belt is rotating in one direction, the foreign matters adhering to the surface of the conveying belt is removed by the wiper. When the conveying belt rotates a predetermined distance in the opposite direction, the pinch roller, the electric charge removing roller and the electric charge supply roller that are in contact with the belt surface are disengaged from the surface of the conveying belt. The predetermined distance is set equal to a rotating distance that the conveying belt rotates until a portion of the surface of the conveying belt, which was in contact with the wiper, comes into contact with the pinch roller, the electric charge removing roller and the electric charge supply roller.
