PROBLEM TO BE SOLVED: To accurately reproduce density gradation in a dot to form a recording image with high resolution by mixing an ink and a dilute solution by an accurate mixture ratio. SOLUTION: First and second nozzles 35, 38 to which a dilute solution and an ink are introduced eject them, respectively. A laminated material layer 32 consisting of a first material layer 41 made from a metallic material having a comparatively good wettability and a second material layer 42 made from a resin material having comparatively little wettability is provided on a main face 31a of a substrate 31 and it is selectively removed to form the nozzles 35, 38. At least one of the ejection directions of the ink and dilute solution is restricted by virtue of the material forming the laminated material layer 32. |
