ABSTRACT:
An image recording apparatus includes a recording head having a plurality of element arrays in a scanning direction, a driving device, a transporting mechanism and a selecting device. Each element array includes a plurality of recording elements arranged with a predetermined spacing in a direction approximately perpendicular to the scanning direction. The driving device drives the recording elements of the recording head. The transporting mechanism moves the recording head relative to the recording medium in the direction perpendicular to the scanning direction. The selecting device selects between a first recording mode for performing the recording operation with high resolution and high precision and a second recording mode for performing the recording operation with high speed. When the first mode is selected, the recording head moves to record additional dot lines formed by the recording elements of each element array between initial dot lines formed by the same. When the second recording mode is selected, more element arrays are used than in the first recording mode to perform the high speed recording operation. Further, the first mode reduces effects caused by unevenness of the space between each of the element arrays and fluctuations in scanning speed.
