Using an intermediate transfer body onto which a conductive recording liquid containing water that is ejected by heads is provided; and a potential applying unit which applies a potential which can electrolyze the water within the conductive recording liquid which is ejected from the heads and which temporarily bridges between the heads and the intermediate transfer body, the potential applying unit applies a potential between the intermediate transfer body and electrodes which are in contact with the recording liquid in supplying units which supply the recording liquid to the heads.
