Abstract
An inkjet head includes a plurality of nozzles, a plurality of pressure chambers arranged along a first direction, each of which extends in a second direction crossing the first direction, communicates with one of the nozzles, and has a first end through which ink is supplied and a second end through which ink is recycled, a plurality of ink inlets configured on a side of the first ends of the pressure chambers through which ink is supplied to the pressure chambers, and a plurality of ink outlets configured on a side of the second ends of the pressure chambers through which ink is recycled from the pressure chambers. A flow rate of the ink flowing from a ink inlet to an ink outlet through pressure chambers that are at the ends along the arrangement positions of the pressure chambers is higher than a flow rate of the ink flowing from an ink inlet to an ink outlet through pressure chambers that are at the center along the arrangement positions of the pressure chambers.
