Ink jet print head and ink jet printing apparatus

Abstract

An ink jet print head is capable of creating a state where the direction of ink-drop ejection is not likely to be influenced by air currents generated by the ink ejection, and is capable of printing an image without causing the shifting of dots. To this end, air currents generated by the ejection of ink and the interference among the air currents are reduced by blowing out gas in a direction parallel with the direction of the ink ejection. Accordingly, even with a print head that ejects, at high ejection frequency, ink from multiple ejecting openings formed densely, the advancing direction of the ink drops is unlikely to be deflected. As a consequence, a high-quality, uniform image can be outputted.
