Abstract
An ink dot printer includes a recording electrode and an operating electrode disposed in a mutually opposing relationship with a record medium interposed therebetween, and a potential difference is caused to appear between the electrodes so that ink around an end of the recording electrode is flown toward the record medium. The recording electrode is formed from a nonconductive member having an ink impregnability which is processed to provide electric conductivity on a surface thereof. Thus, an electric field is well concentrated at the end of the recording electrode, thereby assuring flying of ink from the end of the recording electrode to improve the stability of printing.
