PROBLEM TO BE SOLVED: To provide a cleaning device for enabling a cleaning work by using an ink roller cleaning unit even without providing a special purpose cleaning unit for a moistening water supply means or a blanket cylinder. SOLUTION: Each part before cleaning is initialized after a printing work is finished at a step S1. A cleaning liquid is discharged onto the ink roller by a discharge means at a step S2. When a prescribed time is elapsed, a form- dampening roller is contacted at a step S3. A blade means is contacted with the ink roller to start scraping of the contaminated liquid at a step S4. Thus, the ink roller is sequentially cleaned by the liquid. Meanwhile, since the liquid is supplied onto the form-dampening roller via a surface of a printing plate, the surface is sequentially cleaned. When the roller is cleaned for a prescribed time, discharging of the liquid is stopped at a step S5. The form-dampening roller is separated at a step S6, the blade means is separated at a step S7, and then the cleaning work is finished.
