    摘要: 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.

    摘要: An image forming apparatus with a voltage applying unit between a recording head and an intermediate transfer drum is capable of activating polyvalent metal ions inactivated in advance in jetted recording liquid without liquid activators independent of the recording liquid for sufficient flocculation on the drum. When the jetted recording liquid temporarily bridges the head and the drum, electrolysis of the recording liquid by the voltage applied instantly leads to generation of hydrogen ions on the drum, which triggers a sequence of reactions in the recording liquid of activation of polyvalent metal ions, cross-link between the activated polyvalent metal ions and anionic polymer, and increase in viscosity on the drum.
