Image Number 2 for United States Patent #6563526.
An image formation apparatus which records an image on a recording medium has a recording element array head on which plural recording chips are disposed, and in the recording chip plural recording elements are arrayed. A main scan unit is for scanning the recording elements, and a sub-scan unit, for effecting relative motion between the recording medium and the recording chips in a sub-scanning direction. The main scan unit scans the recording elements n (n.gtoreq.2) times on the basis of image data corresponding to one scan. The direction along which the recording elements are disposed, is deviated from the direction perpendicular to the sub-scanning direction, by a predetermined angle.
