Abstract
Disclosed is a raster data drawing apparatus, in which a reference clock pulse signal having a predetermined period is first generated, and then a plurality of delayed clock signals are generated.

An image is formed in a main scanning direction synchronously with one of the plurality of delayed clock signals so that the starting point of the image in the main scanning direction is adjusted.
