PROBLEM TO BE SOLVED: To improve reliability of ejection of ink drops and to raise a density of nozzles to be formed on a recording head. SOLUTION: A recording head is so constituted that plate-like insulation substrates each having a conductive layer on the surface are laminated with an inner spacer 20 therebetween. A liquid ink 1 is supplied to the face provided with the conductive layer and a voltage is applied to the conductive layer. As a result, supplying of the ink to a tip of a nozzle 14 can be assured and sticking of a coloring agent in the ink to the nozzle can be prevented. Nozzle arrangement with high resolution can be achieved and the head having sufficient strength can be realized. |
