Abstract
A first image data selective output section selects odd-numbered image data of the second raster scan line from a memory section to cause a first exposure section to form an electrostatic latent image on a photoconductor drum. At the same time, a second image data selective output section selects even-numbered image data of the first raster scan line from the memory section to cause a second exposure section to form an electrostatic latent image on the photoconductor drum. In the second main scanning operation, positions of light beams are moved by an amount of one raster line in a sub-scanning direction so that the first image data selective output section forms odd-numbered image data of the third raster line and at the same time, the second image data selective output section forms even-numbered image data of the second raster line.
