A head maintenance device includes a wiping section which wipes a nozzle plane, on which a plurality of nozzles to eject ink are provided, of an inkjet head. The wiping section includes a wiping member including a cloth, an elastic body and a support, in the order named from a side where the wiping section comes into contact with the inkjet head. The cloth is moved parallel to the nozzle plane at a relative moving velocity of not less than RMV×0.2 and not more than RMV×0.9 with respect to the nozzle plane so as to wipe the nozzle plane.
摘要:
A method of forming an image containing the step of: ejecting droplets of an ink-jet ink containing water, a colorant and a polymer through a nozzle of an ink-jet head onto an image recording medium, wherein the polymer has a hydrophilic main chain and a plurality of side chains which are capable of cross-linking between the side chains by irradiation with an active energy ray; and a shearing stress is continuously applied to the ink-jet ink in an ink-jet head channel of the ink-jet head during the time when the ink-jet head is in a stand-by condition to eject the droplets of the ink-jet ink.
