ABSTRACT:
An image forming apparatus has a scanning unit capable of forming a plurality of lines of an image simultaneously by scanning, in a main scanning direction, laser beam that has been emitted from a plurality of laser emitting devices. The apparatus has a memory for storing an error characteristic, in a sub-scanning direction with respect to an ideal scanning line in the main scanning direction, of a scanning line scanned by the scanning unit. A line on which image data is read out is changed over in accordance with a line changeover position in the main scanning direction based upon the error characteristic and a revised pixel position in the main scanning direction in the image data.
