Abstract
An ink jet recording device for applying an electric force to an ink to cause an ink particle to fly onto a recording medium for recording, comprises: a control substrate arranged so as to face the recording medium, said control substrate comprising an insulating supporting substrate, and first and second control electrodes arranged on both sides of the insulating supporting substrate, said control substrate having at least one through hole which passes through said first and second control electrodes and said insulating supporting substrate; ink supply source for supplying an ink into said through hole of said control substrate; and signal voltage supply source for applying a signal voltage between said first and second control electrodes, in accordance with a picture signal for causing an ink particle to fly out of said through hole toward said recording medium.
