To provide an ink jet head capable of performing proper image forming operations by easily removing air bubbles contained in ink. A manifold 13, 14 is formed with an ink supply channel 41. A plurality of openings 45 are formed at one edge of the ink supply channel 41. The openings 45 are fluidly connected to ink channels 31. The openings 45 have a smaller dimension toward the ink channels 31. During purging or flushing operations, an air bubble EB in the ink supply channel 41 is pulled toward the ink channels 31 while gradually changing it outer shape in the opening 45. In this way, the air bubble is smoothly and easily pulled into the ink channel 31, and ejected through a nozzle 16a.
