<p><P>PROBLEM TO BE SOLVED: To provide an image forming apparatus capable of printing an oblique line image faithfully while improving the aspect ratio of an printed image furthermore. <P>SOLUTION: The image writer comprises a light emitting element array unit having a plurality of light emitting element arrays each including a plurality of light emitting elements arranged in one direction and being subjected to emission control depending on binary image data, and an image data transfer control means for transferring image data to the light emitting element array unit wherein the plurality of light emitting element arrays are arranged in zigzag such that they are shifted by a predetermined amount in the sub-scanning direction and overlapped by a predetermined amount in the main scanning direction, i.e. the axial direction of a photosensitive body, the image data transfer control means divides a line of image data for each light emitting element array and transfers the divided image data to each light emitting element array thus writing the image data. When a line of image data is transferred to each light emitting element array during one main scanning line, the image data transfer control means performs image data transfer control such that an operation for transferring odd pixel data after transferring even pixel data is repeated a plurality of times. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
