Abstract
An image forming apparatus wherein data which enters in parallel a plurality of pixels at a time is converted to a serial image data string. This serial image data string is shifted by a predetermined number of pixels, the shifted serial image data string is output in parallel a plurality of pixels at a time, and an image is formed based upon the image data output in parallel a plurality of pixels at a time.
Claims23
An image forming apparatus comprising:
- first converting means for converting image data, which enters in parallel a plurality of pixels at a time, to a serial image data string;
- shifting means for shifting, by a predetermined number of pixels, the serial image data string output by said first converting means, wherein the predetermined number of pixels equates to an amount of adjustment for correction of an image position;
- second converting means for converting the serial image data string, which has been output by said shifting means, to parallel image data a plurality of pixels at a time;
- and
- image forming means for forming an image based upon the image data output by said second converting means in parallel a plurality of pixels at a time.
