Abstract

PURPOSE: To improve the quality of a picture by making the intensity of diameter of a light beam on a scanning line at the boundary between a picture part and no- picture part in the subscanning direction lower than that in a no-picture part or picture part beyond the boundary.
CONSTITUTION: When character P is recorded by the P-P system, the character is recorded at boundary part A1, where a change from a picture part to a no-picture part is made in the subscanning direction, during the recording of the 1st line i+1 scanning the no-picture part by making the output level of a laser beam lower than that in a no-picture part at any other part corresponding to picture information on scanning line (i) in a picture part right before it. Further, recording is carried out in the same method at the boundary part A2 where a change from a no-picture part to a picture part is made in the subscanning direction. Thus, the output level of a light beam is decreased at a boundary part between a no-picture part and picture part in the subscanning direction during a scan wherein an influence of unevenness of illuminance of the light beam is possibly exerted, so that picture recording of high quality will be enabled.
