Inkjet recording apparatus

摘要

An inkjet recording apparatus includes an insulating support member (101, 102) having a major surface on which a plurality of ejection electrodes (103) are formed with each of the ejection electrodes protruding from an ejection end of the insulating support member. Each of the ejection electrodes is coated with an insulating material (109). Further, a cover member (105, 401, 402) is provided to cover the insulating support member to form ink chambers (113, 114) between them and an opening (107, 403) at an ejection end of the cover member. The ejection portion of each ejection electrode protrudes from the ejection end of the cover member through the opening. The ink is supplied from one ink chamber to the ejection electrodes and flows into the other ink chamber through the ejection electrodes. <IMAGE>
