ABSTRACT:
An inkjet recording apparatus includes: a recording head that moves in a main scanning direction and ejects ink from a plurality of nozzles toward a recording medium to perform a main scan; a conveying mechanism that conveys the recording medium in a sub-scanning direction by a predetermined conveyance amount to perform a sub-scan; and a control unit that controls the recording head and the conveying mechanism to repeat the main scan and the sub-scan alternatively to eject the ink on the recording medium at a position upstream in the sub-scanning direction with an interval satisfying a required resolution from the ink ejected on the recording medium in a previous main scan, the control unit setting the predetermined conveyance amount greater than a theoretical conveyance amount set based on a number of the nozzles being used and the required resolution.
