摘要： PROBLEM TO BE SOLVED: To provide a cleaning device of an inkjet printer, which has a high cleaning effect, can achieve sure disposal of waste ink with a simple structure, and causes no deterioration of image forming quality due to stain of the inside of a device or clogging of nozzles.
SOLUTION: By driving the cleaning device in which a wiper and an air jetting nozzle are integrated, the wiper is moved under a state where it is brought into contact with an ink delivering face while air heated by a heating means is jetted from an air jetting nozzle. The wiper scrapes off and collects ink drops on the ink delivering face and ink fixed thereon. By jetting the heated air, viscosity of the ink drops on the ink delivering face is made low, and then the ink drops are fed to the wiper rapidly and collected along the wiper, so that sure removal of the ink is performed without lowering a cleaning speed.
