Abstract
An end tip part of one side of plural recording electrodes are disposed insulated from one another facing a recording surface of recording medium, and these electrodes are inserted into plural plate-or film-shaped solid state dielectric porous or non-porous substance substrates, and an auxiliary electrode is disposed on one or both outer surfaces of this solid state dielectric substance substrates, and a fluid ink is fed to this recording head, and also signal voltage is applied across the recording electrode and the auxiliary electrode, thereby the electroosmotic travelling of fluid ink is carried out, the fluid ink forming this ink pattern is to fly and deposit onto the recording medium by means of coulomb force or electroosmotic pressure.
