Abstract
An ink jet recording apparatus includes an inking medium containing a liquid electrolyte. A chamber is provided for accommodating the liquid inking medium and having a pair of electrodes disposed therein. A signal generator is provided for applying to the pair of electrodes an electrolyzing signal for electrolyzing at least a portion of the electrolyte contained in the inking medium, and a subsequent discharge signal for effecting a discharge explosion of gases produced as a result of the electrolyzing signal. The inking medium is discharged from the chamber in response to the discharge explosion pressure resulting from the application of the electrolyzing and discharge signals.
