ABSTRACT:
A new nozzle structure is disclosed for an ink ejection head of an electric field on-demand type ink jet printer. A plurality of circular nozzles and first electrodes integral with the nozzles are arranged along the widthwise direction (X direction) and feed direction (Y direction) of a sheet of paper. A plurality of lead terminals are individually connected to the arrays of the first electrodes each of which extends in the Y direction. Second electrodes are located at the rear of the first electrodes and individually connected to the arrays of the first electrode each of which extends in the X direction. A third or counter electrode is positioned in front of the first electrodes and at the back of the sheet. Each of the second electrodes is mounted on a nozzle plate or a nozzle support. The first electrodes are supplied with voltage pulses corresponding to image data, the second electrodes for printing with a voltage opposite in polarity to the voltage pulses, and the second electrodes for non-printing with a zero voltage or a voltage common in polarity to the voltage pulses sequentially and repeatedly on the time sharing basis. The third electrode is applied with a constant voltage of the opposite polarity to the voltage pulses.
