Abstract
The emission level of a laser source at the non-imaging time when image data “0” is input and the emission level at the imaging time when image data “1” is input are controlled so that each of them becomes a desired level. The light output intensity is stabilized at all times regardless of variations in ambient temperature. As a result, images uniform in density can be obtained.
