Abstract: PROBLEM TO BE SOLVED: To prevent an ink discharge face from being damaged and to improve a cleaning effect near ink discharge holes in an inkjet head which discharges ink for imaging from ink discharge holes onto a recording medium. SOLUTION: In the method for cleaning a printing head which has the ink discharge face 6 where an array of ink discharge holes 13 is set for discharging the ink of one color or a plurality of colors color by color, a cleaning roller 7 formed of a material having either of independent bubbles and continuous bubbles into a cylindrical shape is moved relatively in a state in which the cleaning roller is kept in touch with the ink discharge face 6 of the printing head, and an ink 15 in the ink discharge holes 13 is sucked by a pressure change in the ink discharge holes 13 at a time when an outer circumferential face of the cleaning roller 7 moves in touch with the ink discharge face 6. Accordingly, the ink discharge face 6 is prevented from being damaged. Moreover, the sucked ink 15 is absorbed into holes formed by bubbles, so that the cleaning effect near the ink discharge holes 13 can be improved. COPYRIGHT: (C)2003,JPO
