Abstract
An ink jet recording apparatus includes a recording head having one nozzle array or a plurality of nozzle arrays. Each nozzle array includes a plurality of nozzles. These nozzles include at least one end nozzle at at least one end of the nozzle array or arrays and ink nozzles other than the at least one end nozzle. The end nozzle discharges a windshield liquid and the ink nozzles discharge ink. The end nozzle prevents the displacement on a recording medium of ink droplets discharged from the outermost ink nozzle among the ink nozzles, thus forming a high-quality image without partial unevenness in recording density.
