ABSTRACT:
A drive method of an ink-jet head is provided in which a diaphragm is deformed by means of electrostatic force to eject an ink droplet from a nozzle so as to prevent a residual charge from being created between a diaphragm and an individual electrode. The method has first and second drive modes. In a first drive mode a voltage of a first polarity is applied between a diaphragm of the inkjet head (common electrode) and an individual electrode to cause the diaphragm to be deformed and an ink droplet to be ejected from a nozzle. In the second drive mode a voltage of a second polarity opposite to the first polarity is applied between the diaphragm and the individual electrode to cause the diaphragm to be deformed and an ink droplet to be ejected from the nozzle at least once for each operation of ink droplet ejection performed in the first drive mode. According to this method, a residual charge created between the diaphragm and the electrode can be removed concurrently with performing the operation of ink droplet ejection by applying positive and negative drive voltage pulses.
