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.

Abstract: PROBLEM TO BE SOLVED: To solve a problem wherein in handling tile image data, a conventional method of correcting bending for bit map image data cannot be applied as it is. SOLUTION: An image forming apparatus reads the tile image data including overlap of a line of interest and a line switching part in accordance with the bending of a scanning line, and stores the data into a specified position of a line buffer. A level difference of the line switching part in the image data read from the line buffer is smoothed to form an image, based on the line switching when storing the image data into the line buffer. Thus, when the image data of the processed tile occur in the line buffer, the image data of the tile are replaced with the image data of the tile located under the processed tile, with the image memory.
