Abstract (en)

[origin: EP0778135A2] In an electrostatic ink jet recording device, an ink chamber stores liquid ink containing charged toner particles. An ejection opening or slit is formed in one end portion of the ink chamber. An electrophoresis electrode is positioned at the other end portion of the ink chamber facing the one end portion. A plurality of record electrodes are arranged in parallel in the ejection opening. A counter electrode faces the record electrodes with the intermediary of a path for transporting a recording medium. Discharging means is located upstream of the counter electrode with respect to the intended direction of medium transport. The discharging means dissipates any undesirable charge deposited on the recording medium before the medium reaches the counter electrode. <IMAGE>
