Abstract: An image forming apparatus includes DMA control units each of which is provided with DMA controllers. Each DMA controller is provided with a plurality of data buffers respectively corresponding to different addresses in a subscanning direction. Each of a predetermined number of pixel data in a main scanning direction is stored in an associated one of the data buffers. Pixel data stored in each of the data buffers are output to an image memory based on the address in the subscanning direction, which corresponds to the associated data buffer.

Abstract: An optical scanner includes a light source modulated based on image data, an optical deflection and scanning part deflecting a light beam emitted from the light source, and a scanning and imaging optical system condensing the deflected light beam toward a scanning surface so as to form a light spot optically scanning the scanning surface. The effective scanning region of the scanning surface is divided into a plurality of regions according to a scanning line curving characteristic. Suitable image data for optically scanning the divided regions are selected from image data of a plurality of image lines every time the light spot optically scans the effective scanning region, so that the image data of each of the image lines is written with scanning line curving being corrected.
