PURPOSE:To prevent the drop of the recording quality without cost-up by providing first deflecting electrodes rectangular to the direction of the mutual movement of the record paper and the head and secod deflecting electrodes parallel to said direction. CONSTITUTION:The ink-jet head is provided with nozzles 2, charging electrodes 3 giving a charge to the ink droplet 5 from the nozzles 2, first deflecting electrodes 4 opposing rectangularly to the direction of the movement of the recording paper 8, second deflecting electrodes 9 parallel to the direction of the movement and gutters 7. As a base plate a di-acrylphthalate resin including glass fibers is used, the electrodes 3, 4, 9 and gutters 7 are formed in a body by a compression molding method, together with the lead-pattern of the electrodes on the back surface by a photo-etching method. Thereby the drop of the recording quality is prevented without cost-up and the change of the recording speed is capable to follow the change of the ink characteristics. |
