Abstract
Disclosed is a multi-beam image forming system, which has a light emitting unit including a plurality of light sources emitting a plurality of beams, and a table carrying a photosensitive film on which an image is formed with the plurality of beams. A sensor is provided on the table, and light amount of each of the light sources is detected by moving the table and the light source relative to each other. Further, based on the detected light amount of each of the light sources, compensation values are determined. The compensation values are used when the light sources are driven so that the light amount on the photosensitive film accurately corresponds to an image data.
