A laser generating apparatus inputs to a laser scanner as modulating data a signal indicative of the logical sum of serial data corresponding to image information and an arbitrarily delayed version of the serial data. Thus the laser scanner modulates the laser beam in accordance with on and off intervals of the modulating data and irradiates the modulated beam onto a photosensitive body to scan the same. Therefore, changes in the laser exposure width due to fluctuations of the surface potential (mainly, the exposure potential) of the photosensitive body are easily and certainly corrected in accordance with the adjustment of the on and off intervals of the modulating data, namely, the adjustment of the quantity of data delay.
