摘要： An inkjet head and an inkjet printer having the inkjet head are disclosed. In accordance with an embodiment of the present invention, the inkjet head includes a chamber housing ink and a nozzle, which discharges the ink housed in the chamber. Here, a plurality of inner wall grooves are formed on an inner wall of the nozzle, in which the plurality of inner wall grooves extends in a lengthwise direction of the nozzle. Thus, the inkjet head can discharge big ink droplets at a high frequency by quickly filling the ink in the nozzle after relatively big ink is discharged.
