    摘要: In the method for scanning light beam in a xerographic recording using a laser light beam spots to scan on a photoreceptor the quality of the recorded image is improved by increasing size of the light beam spot when the irradiation spot scanning on the photoreceptor has neighboring spots to be irradiated. For detecting whether the neighboring spots are the spots to be irradiated or not, three shift registers 12, 13 and 14 and a NOR circuit 15 are used, and the output of the NOR circuit controls analog circuit 161 which switches amount of the laser current.
