Cleaning method and inkjet recording apparatus

Abstract

A cleaning method is a method of cleaning a recording head that has an ink-ejecting surface and ejects ink from the ink-ejecting surface. The cleaning method includes supplying a cleaning liquid to the ink-ejecting surface of the recording head, and wiping the ink-ejecting surface of the recording head twice with a wipe blade after the supplying a cleaning liquid. A first wiping speed in the wiping is 5 mm/sec or more and 25 mm/sec or less. A second wiping speed in the wiping is 45 mm/sec or more and 100 mm/sec or less. The cleaning liquid contains water, a water-soluble organic solvent, an amphoteric surfactant having a betaine structure, and a silicone surfactant. The viscosity of the cleaning liquid is 1.0 mPa·s or more and 3.1 mPa·s or less. The static surface tension of the cleaning liquid is 10 mN/m or more and 25 mN/m or less.
