Abstract
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.
