Abstract
The present invention provides a printing device wherein drying of ink in a recording electrode and resulting choking of the recording electrode can be prevented and ordinary ink can be used. The printing device includes a recording electrode which has formed at the center of the section along the entire length thereof a narrow hole for sucking and supplying ink to a front end portion of the recording electrode by a capillary phenomenon. The recording electrode further has a through-hole formed therein and communicating with the narrow hole and a rear end portion of the recording electrode so that ink may be supplied at a high speed from the narrow hole to the end portion of the recording electrode by a capillary phenomenon. Drying of ink is prevented by the fact that ink comes around in the through-hole communicating with the narrow hole.
