Abstract
A continuous type liquid ejection head includes an ejection opening plate formed with ejection openings, from which a pressurized liquid is ejected, and a deforming unit. The ejection opening plate is made of an elastic plate containing a rubber material, at least at portions that are formed with the ejection openings. The deforming unit is arranged adjacent to the ejection opening plate and is configured to deform the elastic plate so that areas of the ejection openings are periodically changed.
