Abstract
The magnification of an image in the main scanning direction thereof is altered by making the frequency of the image clock variable. At this time, if the pre-SOS lighting signal and the APC signal are output synchronously with the frequency of the image clock, then an SOS signal may not be output from the SOS sensor and control of the amount of light of a light beam may not be accurately executed. Therefore, the timings of the outputs of the pre-SOS lighting signal and the APC signal are controlled so as to normally be output at a uniform timing (i.e. the periods from the input of the SOS signal until the outputs of each signal are made uniform).
