<P>PROBLEM TO BE SOLVED: To provide an ink-jet apparatus uniform in thickness of a piezoelectric element film, a method for producing the apparatus, and an image forming apparatus. <P>SOLUTION: The ink-jet apparatus has a substrate, an electrode provided on the substrate, the protrusions provided on the electrode, and an electromechanical conversion film. The electromechanical conversion film is formed through: a step (1) of partially modifying the surface of the electrode or the protrusion; a step (2) of partially applying a liquid by a chemical solution deposition method on the electrode; and drying, thermal-cracking and crystallizing the partially-applied liquid by the chemical solution deposition method. The protrusion comprises an insulating material, is hydrophilic in every face and is formed so as to surround the place on which the above liquid is applied. A water-shedding film is formed on the surface of the protrusion of opposite side of the substrate. In the cross-sectional shape of the protrusion, the width of the surface of opposite side of the substrate is longer than that of the surface of a substrate side. The step (2) is characterized by applying the above liquid so as to contact the surrounding inner face of the protrusion. <P>COPYRIGHT: (C)2012,JPO&INPIT |
