Abstract
An inkjet head may comprise an ejection port which ejects ink and an ink flow path which supplies the ink to the ejection port. The inkjet head may also comprise an ejection actuator which supplies ejection energy to the ink in the ink flow path. The ejection energy may cause the ink to be ejected from the ejection port. The inkjet head may also comprise a wall portion. The wall portion may be located at a position farther from the ejection port along the ink flow path with respect to a position at which the ejection energy is supplied. The wall portion may define an inner wall surface of the ink flow path. The wall portion may deform to decrease a cross section of the ink flow path in a direction orthogonal to an ink-flow direction as a temperature of the ink in the ink flow path increases. The wall portion may deform to increase a cross section of the ink flow path in a direction orthogonal to an ink-flow direction as the temperature of the ink in the ink flow path decreases.
