摘要：
According to one embodiment, a printing apparatus includes an ink-jet head including a nozzle plate with a nozzle string in which a plurality of nozzle holes for discharging ink are arranged, and a cleaning device including an ink-repellent surface with ink repellency which is configured to come in contact with the nozzle plate in a state in which the ink-repellent surface is opposed to the ink-jet head, an ink-affinitive surface with ink affinity which is configured to create a gap between the ink-affinitive surface and the nozzle plate in a state in which the ink-repellent surface is in contact with the nozzle plate, and to have a smaller ink contact angle than the ink-repellent surface, and a plurality of suction ports formed in the ink-affinitive surface.
