Abstract
A plurality of beams scan the photosensitive body or the like so that a high quality image whose streak is not recognized by a human eye can be formed. 2m lines are formed simultaneously in Nth time, (N+1)-th time, and (N+2)-th time scannings respectively. At this point, the m lines are fed in a sub-scanning direction at each termination of one-time scanning, and the next scanning is performed. Accordingly, a region which is exposed twice between the scannings is generated at an m-line period.
