Abstract
An ink jet printer head includes a substrate having a heat resisting body, an ink chamber barrier installed on the substrate so as to form a side wall of an ink chamber filled with ink introduced through an ink channel, and a nozzle plate having a nozzle hole communicating with the ink chamber and installed on the ink chamber barrier, and an ink separating wall protruding from a periphery of the nozzle hole towards the substrate located on the ink channel to interrupt a flow of the ink is provided in the nozzle plate. The backflow of the ink into the interior of the ink channel and an ink tail generated in the nozzle and a satellite droplet are reduced by using the ink separating wall, thereby improving printing efficiency and printing quality.
