    摘要： An image forming apparatus includes a recording head including a plurality of printing elements each of which offsets at least in an auxiliary-scanning direction one another and ejects droplets toward a recording medium. The image forming apparatus further includes a main scanning unit configured to scan the recording head, relative to the recording medium, in a main scanning direction perpendicular to the auxiliary-scanning direction. The image forming apparatus still further includes a auxiliary-scanning unit configured to scan the recording head, relative to the recording medium, in a main scanning direction perpendicular to the auxiliary-scanning direction. The image forming apparatus still yet further includes a controller configured to control the printing head, the main scanning unit and the auxiliary-scanning unit to form dots in rows arranged in the auxiliary-scanning direction at a first predetermined interval, and columns arranged in the main scanning direction at a second predetermined interval while performing main scans and sub-scans repeatedly. The controller controls the printing head, the main scanning unit and the auxiliary-scanning unit to form first dots in an area of the printing medium at first alternate columns by a first main scan, and to form second dots in the area by a second main scan at second alternate columns different from the first alternate columns. The second dots are shifted, relative to the first dots, a first predetermined distance smaller the first predetermined interval.

    摘要： An image recording apparatus for recording an image on a recording medium by causing a recording head having the arrangement of a plurality of recording elements to conduct its main scanning for the recording medium interrelatedly in the direction opposite to the arrangement of the recording elements comprises setting means to set the number of main scannings by the recording head; main scanning means to perform recording by plural numbers of main scannings with respect to one pixel by causing the recording head to conduct its main scannings for the same recording area of the recording medium in accordance with the number set by the setting means; and sub-scanning means to cause the recording head and the recording medium to be sub-scanned interrelatedly per main scanning in an amount smaller than the width of the arrangement of the recording elements of the recording head. Hence, even if a disabled ejection occurs in one scanning at the time of recording by a multi-scanning, the missing dot is complemented by the following scan to make it possible to obtain an image having no image defectives at all times.

    摘要： A recording head (12) having a plurality of recording elements can operate in a first recording mode for recording a desired image by performing a single scan operation on a predetermined region on a recording medium, and a second recording mode for recording a desired image by recording a thin image a plurality of number of times by performing a plurality of number of times of scan operations on the predetermined region. The scan speed in the second recording mode is set to be higher than that in the first recording mode.
    For example, when the scan speed in the second recording mode is N times that in the first recording mode, the driving operation of the plurality of recording elements is controlled to obtain a dot pattern in which the minimum dot distance in the scan direction in the second recording mode is N times or more that in the first recording mode.
    Image quality can be improved without decreasing the throughput.
