A head cleaning device includes an electrode disposed in a position confronting to a bottom of a head in a cleaning position, the head including nozzles for discharging a water-soluble ink, the electrode being set in a covered state to provide a surface covered with an electrolyte which, when electrolyzed, dissolves the water-soluble ink. A liquid supplying unit supplies the electrolyte to the electrode so that the electrode is set in the covered state. A voltage supplying unit supplies a voltage between the head and the electrode to electrolyze the electrolyte on the surface of the electrode in the covered state.
