ABSTRACT:
A device applicable to a laser beam printer, color printer, digital copier, facsimile machine or similar image recorder for controlling the output level of a scanning beam to a predetermined level. The device sets the output level of the scanning beam in response to data fed thereto from the outside, thereby coping with changes in image forming conditions and changes in various characteristics due to aging. The device incorporated in a color printer, for example, sets the output levels of individual laser beams in matching relation to the characteristics to individual colors.
