PROBLEM TO BE SOLVED: To provide a regeneration method for an inkjet head in which regeneration of nozzle clogging is possible in a short time and simply without a solvent shock because of a coating liquid and a solvent for cleaning being brought about in maintenance of a nozzle inner surface, and moreover in which use of a cleaning liquid can be reduced, and to provide an apparatus. SOLUTION: In the nozzle regeneration method and apparatus for the inkjet head, a foreign substance as the cause of clogging of nozzle holes is selectively removed by polishing a part or the whole of an ejection surface of the inkjet head, at the nozzle holes which are clogged by the foreign substance such as dried ink and become defective in ejection in a nozzle part which ejects the ink of the inkjet head. Thus an ejection defective part of the nozzle part is regenerated. COPYRIGHT: (C)2008,JPO&INPIT
