Abstract
A beam position detector output processor converts an output from a beam position detector into beam position information. A main control unit detects a total offset value of a plurality of operational amplifiers constituting the processor. The detected offset value is used to compensate a determination reference value used to control the sub-scanning position of a beam, or the beam position information obtained from the beam position detector output processor. As a result, the offsets of the operational amplifiers constituting the beam position detector output processor are compensated.
