Abstract
A recording laser beam is intensity-modulated and is caused to scan a photosensitive recording material in both the main and sub scanning directions. The position of the recording laser beam on the recording material in the main scanning direction is detected and position reference pulses are generated each time the laser beam moves along the recording material in the main scanning direction by a predetermined constant distance. The recording laser beam is intensity-modulated only for a predetermined constant time interval between each pair of adjacent position reference pulses and is made essentially null for the rest time interval between the adjacent position reference pulses so that a unit area of the recording material corresponding to one picture element is exposed to the recording laser beam for a predetermined constant time interval regardless of fluctuation in the scanning speed of the recording laser beam.
