ABSTRACT:
An ink jet head, which can prevent non-discharge due to face wetting, has an ink nozzle for discharging ink through a discharge port communicating with the ink nozzle and formed in a water-repelling surface. A hydrophilic groove is formed in a nozzle plate in which the ink nozzle is formed to be directed toward the water-repelling surface in a concave fashion. The hydrophilic groove is provided between plural nozzle arrays and a capillary force of the hydrophilic groove is greater at end portions thereof than at a central portion thereof.
