Abstract

This invention is directed to prevent an ink jet inactivation state which is induced when ink droplets adhering to the jet port surface of an ink jet head reach the jet port, and is characterized by including a water repellent region in the proximity of the jet port disposed on the jet port surface and a groove-like hydrophilic region inside a region spaced apart by a predetermined distance from the jet port and adjacent to the water repelling region. Since the groove-like hydrophilic region is disposed, the ink droplets adhering to the jet port surface can be taken into the hydrophilic region. Accordingly, excellent recording can be accomplished even under the condition of high speed recording and high frequency driving.
