摘要： An image forming device comprises a plurality of unit modules arranged in a main scanning direction, each unit module having a light source that modulates according to image data and a deflection unit which deflects the light emitted from the light source to scan a surface to be scanned. Areas scanned with each unit module are joined together to record the image. The image data includes fixed pixel areas in number equal to the number of the unit modules and which have one scanning line in common with the adjacent fixed pixel area, and variable pixel areas that link up the fixed pixel areas. The image data is constructed by adding pixels of each unit module to the variable pixel areas at a record start side or a record stop side of the fixed pixel areas, and the variable pixel areas are commonly shared between two neighboring unit modules.

摘要： In a beam-spot position compensation method for use in an optical scanning device which scans a surface of a photosensitive medium by a light beam emitted by a light source, a plurality of sections are defined by dividing a scanning region on the scanned surface. An emission timing of the light beam for every section is adjusted so that a spacing between beam-spot positions corresponding to pixels of start and end of each section is changed by a predetermined amount. The sparseness or denseness of beam-spot position spacings of the plurality of sections in the whole scanning region is compensated.
