Abstract
A laser printer can record high definition and high quality images without requiring any increase of electrical and mechanical design precision for increasing a scanning line density thereof. The laser beam is deflected in a primary scanning direction and a subsidiary scanning direction. With such scanning, an artificial scanning line along an edge of a recording image can be established for accurately recording an oblique line, a curved line, a barbel portion of a character, a half-tone image or so forth.
