A liquid jet printing head includes a discharging outlet for discharging printing liquid, an energy generating element capable of generating an energy for discharging the liquid through the discharging outlet and a discharging outlet face at which the discharging outlet is arranged, characterized in that the discharging outlet face has a water repellent material layer with fine particles of an inorganic material distributed in a water repellent resin in a desired distribution state. A liquid jet printing apparatus is provided with the liquid jet printing head. The liquid jet printing head enables one to always perform stable ink discharging thereby providing high quality printed images.
A liquid jet printing head includes a discharging outlet for discharging a printing liquid, an energy generating element for generating energy for discharging said liquid through said discharging outlet and a discharging outlet face at which said discharging outlet is disposed, characterized in that said discharging outlet face has a water repellent material layer comprising a plurality of fine particles of an inorganic material distributed in a water repellent resin in a desired distribution state wherein an amount of said fine particles of said inorganic material contained in said water repellent material layer is in a range of between 7 and 15 parts by weight versus 100 parts by weight of said water repellent resin and wherein some of said inorganic material fine particles are spacedly protruded at a surface of said water repellent material layer.
