Abstract
In a common chamber () for distributing, to respective pressure chambers (), an ink supplied from the ink inlet (), resistant walls () are provided in areas that are located ahead and behind of the flow of the ink, i.e., areas around inlets of flow channels () that lead to respective pressure chambers (), and any resistance against the flow of the ink is generated according to the heights of the resistant walls (), thereby capturing a solid ingredient () included in the ink. In this case, by adjusting the heights of the resistant walls () to control capabilities of introducing the solid ingredient (), it becomes possible to dispense desired amounts of the solid ingredient () to the respective pressure chamber ().
