Abstract
An ink jet recording apparatus uses a recording head having discharge ports to discharge ink, and records by discharging ink from the recording head while enabling said recording head to travel in the direction of main scan. This apparatus comprises a recording head which is provided integrally with a plurality of recording units having a plurality of discharge port arrays for discharging ink of different colors, respectively, and then, the plurality of recording units are arranged in the direction of main scan to discharge ink of different densities, respectively. With the structure thus arranged, the recording in all the colors is not executed at a time thus making it possible to obtain an excellent image with a lesser deterioration of image due to ink blur and the like.
