ABSTRACT:
An ink jet head ejects ink by utilizing an electrostatic force to fly the ejected ink towards a recording medium. The ink jet head includes an ejection port substrate having ejection ports bored therethrough, a head substrate disposed at a predetermined distance from the ejection port substrate so as to define an ink flow path between the ejection port substrate and the head substrate, channel separation walls disposed on the head substrate, and ejection electrodes for controlling the ejection of the ink. In this ink jet head, each of the channel separation walls and each of the ejection electrodes are arranged in a position corresponding to each of the ejection ports.
