Abstract:
A refresh ink ejection device comprising an ink ejection means for generating and ejecting a refresh ink droplet, an ink collector for collecting the refresh ink droplet, and a deflecting means for deflecting the refresh ink droplet ejected from the ink ejection means so that the refresh ink droplet impinges on the ink collector wherein the deflecting means includes:a conductive member including the ink collector provided on a surface of the conductive member, facing the recording medium, said conductive member and said ink collector having the same potential as ink that the ink ejection means holds, the conductive member being disposed in vicinity of where the ink droplet is generated; a back electrode disposed behind a recording medium; and a voltage application means for applying a voltage between the conductive member including said collector and the back electrode for generating a deflecting electric field; whereby the ink droplet ejected from the ink ejection means is deflected by the deflecting electric field and then impinges on the ink collector.
