ABSTRACT:
A voltage is applied to a plurality of electromechanical transducers mounted on a plurality of nozzles, respectively, so that a meniscus may be formed at the nozzle tip. One or more opposing electrodes or rear transducers are disposed in opposed relationship with a predetermined number of nozzles, respectively, the number of the opposing electrodes or rear transducers being less than that of the nozzles. When one of the opposing electrodes or rear transducers which is in opposed relationship with the nozzle whose transducer is applied with a voltage is applied with a voltage, an ink drop is issued. The opposing electrodes are applied with a voltage in a time-division manner.
