发明名称 Liquid ejecting head and ink jet printing apparatus
摘要 The present invention provides a liquid ejecting head which inhibits the possible generation of satellites and possible inappropriate ejection during liquid ejection, enabling printing with improved image quality and reliability. Thus, ejection openings in the liquid ejecting head each selectively have projections or a circular shape depending on the characteristics of a liquid to be ejected.
