An inkjet head cleaning device and a cleaning method, and an inkjet printing device of the present invention have an object to control properties of mixed liquid of ink and cleaning liquid to clean a nozzle surface with no remaining liquid. In order to achieve such an object, an inkjet head cleaning device according to an aspect of the invention is an inkjet head cleaning device, an inkjet head having a nozzle surface on which nozzles for ejecting ink are arranged, including wiping member traveling means allowing a wiping member of elongated shape having absorbency to travel along a conveying path in a longitudinal direction, cleaning liquid supply means supplying a cleaning liquid to the wiping member, pressing means pressing and bringing the wiping member supplied with the cleaning liquid to and into contact with the nozzle surface, and sliding means sliding the pressing means along the nozzle surface, in which the nozzle surface is cleaned by way of putting a state of a mixed liquid of the ink and the cleaning liquid at a contacting portion between the wiping member and the nozzle surface into a state satisfying a predetermined relationship represented by a relationship between a surface tension and viscosity of the mixed liquid. |
