ABSTRACT:
A recording electrode and an opposed electrode are so positioned as to confront each other through a recording medium, and a recording signal is applied to the recording electrode while a signal reverse-biased with respect to the recording signal is applied to the opposed electrode, so that the potential difference between the recording electrode and the opposed electrode is increased in a state where the respective voltages applied to the mutually confronting electrodes are maintained at low values, thereby sputtering ink from the fore end of the recording electrode in a satisfactory manner without the necessity of any particular process for insulation of the individual components.
