Abstract
An optical scanning device emits a scanning laser beam which scans a photoconductive material, and a detection device located upstream with respect to the scanning direction of the laser beam. The laser beam is first emitted to scan the detection device, and the reception of the laser beam is detected by the detection device. The emission of the laser beam is terminated as soon as the detection device first detects the reception of the laser beam. A scanning laser beam modulated with image information is then emitted to scan the photoconductive material.
