Abstract
An electrostatic ink jet head has a head substrate, an insulating substrate having at least one through hole, an ink guide, ink supply means, a control electrode, and meniscus control means. An ink passage is formed between the head substrate and the insulating substrate. The meniscus control means controls fixing of an edge portion of an ink meniscus formed in proximity to the through hole or within the through hole. With the meniscus control means, it becomes possible to maintain the position and shape of the ink meniscus with stability, thereby allowing ejection and flying of liquid droplets, such as ink droplets, with stability and formation of an image of high quality on a liquid droplets reception member such as a recording medium.
