Abstract
A beam scanning printer which includes a light mixing device for mixing green, red and blue rays radiated from three LEDs with each other and directing the mixed beam to a common converging optical system along a common optical axis is provided. Through the common converging optical system, a beam spot that is common to the three colors is formed. The common beam spot is scanned through a polygonal mirror across a photosensitive material in a main scanning direction as the photosensitive material is moved in a sub scanning direction transverse to the main scanning direction, to record a full-color image on the photosensitive material.
