Abstract
An ink jet head includes ink ejection outlet for ejecting ink, a plurality of heat generating resistors for generating thermal energy contributable to ejecting the ink, and ink flow path comprising the plurality of the heat generating resistors and being in fluid communication with the ejection outlet, the heat generating resistors generating the thermal energy upon receiving a driving signal, so that a bubble is generated in the ink within the ink flow path to eject the ink through the ink ejection outlet; wherein the plurality of the heat generating resistors are arranged in parallel, relative to the ink ejecting direction, in the ink flow path, and the distances from the heat generating centers of the heat generating resistors to the ejection outlet are different.
