ABSTRACT:
The inkjet head ejects ink droplets through ejection nozzles with pressurizing elements and includes ink channels and ink circulation paths. Each ink channel is provided in a gap between a substrate and a nozzle plate and closed at one end and permitting ink to be supplied at another end and flow toward an ink pressurizing zone where the pressurizing element and the ejection nozzle of the nozzle plate are positioned on wall surfaces in the ink channel. Each ink circulation path is provided in the ink channel such that ink pressurizing energy which has been produced by pressurizing the ink with the pressurizing element and which is traveling from the ink pressurizing zone toward downstream of ink supply flow is allowed to propagate toward more upstream of the ink supply flow than the ink pressurizing zone, whereby the ink pressurizing energy is returned toward the ink pressurizing zone. The inkjet printer mounts the inkjet head.
