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.
Claims17
A method of ink jet recording comprising the steps of:
- discharging an ink from a recording head having at least one nozzle array including a plurality of nozzles for performing recording on a recording medium;
- and
- discharging a liquid other than ink from at least two nozzles of the at least one nozzle array of the recording head, wherein the ink is discharged from inner nozzles of the at least one nozzle array and the at least two nozzles for discharging the liquid are disposed at outside of the inner nozzles in the at least one nozzle array.
An ink jet recording apparatus comprising:
- a recording head comprising at least one nozzle array including a plurality of nozzles, the plurality of nozzles comprising nozzles for discharging an ink and nozzles for discharging a liquid other than ink,
- wherein the liquid other than ink is discharged from at least two nozzles of the at least one nozzle array and the ink is discharged from inner nozzles adjacent to the at least two nozzles to perform recording onto a recording medium, the at least two nozzles being disposed at outside of the inner nozzles in the at least one nozzle array.
