Abstract
In an image forming apparatus, a scanning optical system forms on a photosensitive member N beam spots. Each beam spot scans along a scan line on the photosensitive member for one cycle. A center-to-center distance of any neighboring two beam spots is separated by M scan lines. M is a natural number larger than or equal to two. For each cycle, the memory controller reads adjacent sets of line data for N scan lines from the page memory, writes the adjacent sets of line data for N scan lines to the storage areas identified by a plurality of successive addresses of the line memory, selects addresses identifying storage areas storing unadjacent sets of line data having non-successive two scan lines separated by M scan lines; and outputs the unadjacent sets of line data stored in the storage areas identified by the selected addresses to the N laser emitting members.
