Abstract
An embodiment of an inkjet may include a plurality of nozzles to eject ink, a pressure chamber individually communicated with each nozzle and filled with ink, a pressure generator to eject ink by applying pressure to the pressure chamber, an inlet including a narrow portion with a flow path narrower than the pressure chamber and structured to supply ink to the pressure chamber, and a circulation flow path structured to discharge ink in the pressure chamber from near the nozzle. Viscosity resistance of the circulation flow path may be smaller than viscosity resistance of the nozzle, and impedance of the circulation flow path may be equal to or more than 0.5 times of the impedance of the inlet.
