英文摘要PURPOSE:To control the emission of light in the optimum by storing the minimum value and the maximum value of the driving current of a laser diode, which respectively coincide with the minimum value and the maximum value of a light output, and driving the laser diode between the stored minimum value and the maximum value so that scanning is executed. CONSTITUTION:The laser diode 1 is excited with the driving current IL and outputs a laser beam. The laser beam is made incident on a polygonal mirror 2 to be polarized. By mainly scanning an effective scanned surface 3 on a body to be irradiated 3 such as a photosensitive drum, etc., from the left to the right with the laser beam, a write image can be formed. The output of the laser beam, at such a time, are detected 4 and the driving current values at the time when they respectively coincide with the previously set minimum value and the maximum value are stored in a controller as the minimum value and the maximum value of the driving current value. And at the time of scanning with the laser spot, the laser diode 1 is controlled to be driven between the stored driving currents of the minimum value and the maximum value according to the scanning velocity of the laser spot. Then, the light output from the laser diode can be automatically adjusted according to the scanning velocity.
