Abstract
An ink-jet recording head (10) includes a first head member (16a) in which a first nozzle (30) is formed, and a second head member (16b) in which a second nozzle (30) is formed. The first and second head members (16a,16b) are made of materials having different repellent characteristics against ink material. Even if the first and second nozzle have the same size, ink droplets ejected from the first and second nozzles (30) have respective diameters. This enables the ink-jet head (10) to eject ink droplets having various sizes to print a highly graded halftone image.
