ABSTRACT:
A light source is used in which at least one row of light emitting elements, formed from a plurality of light emitting elements arranged along a predetermined direction, is provided. A plurality of scanning lines is recorded synchronously at one main scan operation and at least one scanning line is formed overlapping with each other in each main scan operation. In order that at least one scanning line is recorded in an overlapping region with the scanning lines overlapping each other by a combination of dots recorded by a preceding main scan operation and dots recorded by a succeeding main scan operation, emission of light from the light emitting elements is controlled based on image data. As a result, even if an error in an amount of movement in a sub-scan direction occurs, linear uneven density does not occur, and therefore, an image of high quality can be obtained.
