ABSTRACT:
A light scanning apparatus that scans a scanned face with a light beam includes an adjusting unit that adjusts the position of a light spot of the light beam formed on the scanned face, and a compensating unit that compensates the light intensity of the light beam at the scanned face due to change caused by the adjustment of the position of the light spot. Accordingly, the light scanning apparatus can reduce or eliminate the deviation in exposure between scan lines of the multi-beam scan method and the deviation in exposure between photosensitive bodies of the tandem type image forming apparatus.
