<p>A heating discharge print head drive method for efficiently causing electric discharge by controlling the timing at which a voltage is applied to a discharge electrode and the timing at which the discharge electrode is heated. The energy is excellently saved, the amount of ions produced is accurately controlled to simply perform gradation recording, and a high-quality image can be created. The method comprises a potential difference setting step of setting a potential difference corresponding to the discharge control voltage between a heating discharge print head having a discharge electrode and heating means for selectively heating the discharge electrode and an opposing electrode opposed to the discharge electrode in such a way that a recording medium writable/erasable by the action of electric charge is interposed between the print head and the opposing electrode so as to produce an electric field and a discharge electrode heating step of allowing the heating means to selectively heating the discharge electrode according to image information. At the head voltage applying step of the potential difference setting step, the timing at which a drive voltage is applied to the discharge electrode is synchronized with the timing of the discharge electrode heating step.</p> |
