Abstract
In an apparatus for recording an image by scanning a recording material with a light beam or a heat beam through rotation of a rotating body having at least one light source or heat source, the output of the light or heat source is controlled to obtain a sharp image free of scanning nonuniformity. A non-recording period on the recording material is detected by use of a combination of a light projector and a light receiver positioned in the rotating body with a light reflector secured near the rotating body, or a combination of a light receiver positioned in the rotating body with a light projector secured near the rotating body, or a combination of a magnetic sensor positioned in the rotating body with a magnet secured near the rotating body. The output of the light or heat source is stabilized by a stabilizing circuit within the detected non-recording period.
