<p>PROBLEM TO BE SOLVED: To provide an ink jet head in which effects of crosstalk between two or more rows of arrayed pressure chambers are reduced by using a simple configuration, and which achieves stable ejection characteristics.SOLUTION: Provided is an ink jet head 1 which comprises: pressure chambers 121 arrayed in two or more rows; and a common ink chamber 141 communicating with all the pressure chambers 121. Each of the pressure chambers 121 is commonly supplied with ink from the common ink chamber 141 via an ink inlet 131a facing the common ink chamber 141, and ink droplets are ejected from a nozzle 111 communicating with an ink outlet 121a of the pressure chambers 121 in accordance with a change of pressure caused inside the pressure chambers 121. The ink jet head 1 includes a damper member 15 inside the common ink chamber 141, and a minimal length distance D connecting the damper member 15 and the ink inlet 131a is smaller than a distance between ink inlets 131a and 131a for neighboring rows.</p> |
