The cleaning apparatus includes a cleaning unit which includes a frame member, a magazine roll provided with a spring brake for a cleaning cloth, a wind-up roll for winding up the cleaning cloth while stepwisely transferring the cleaning cloth by a wind-up torque motor, guide rolls for guiding the cleaning cloth so that the cleaning cloth faces the outer surface of the impression cylinder between the magazine roll and the wind-up roll, and a plurality of air cylinders arranged in parallel and disposed on the rear surface side of the cleaning cloth facing the impression cylinder. The cleaning unit further includes a cleaning cloth press assembly provided with a linear press blade linerally pressing the cleaning cloth against the impression cylinder on the side of the magazine roll, a plate-like guide disposed on the side of the wind-up roll and a surface press pad pressing the surface of the impression cylinder. The surface press pad is disposed between the blade and the plate-like guide. The air cylinder acts to move the cleaning cloth press assembly along a substantially U-shaped guide so that the linear press blade moves substantially on a radial line of the impression cylinder.
