To provide an inkjet head that optimizes the value of ink repellency and ink smoothing property of the nozzle surface of the inkjet head, well separates a recording liquid and a wiping blades has a low application force.

An adsorption prevention layer having ink repellency and an ink smoothing property against a recording liquid is formed on the nozzle face on which nozzles to discharge the recording liquid containing a resin and a dye are arranged. The repellency of the adsorption prevention layer improves the separability of the recording liquid and protects the surface of the recording medium against stains by making the angle of fall in the recording liquid 25 μl at 20° or lower. Wear is prevented by reducing the pressing force of the wiping blade against the nozzle face and durability against wiping is secured.
