Abstract
An optical scanning device comprises: photoreceptors corresponding one-to-one to solid colors; high-resolution light sources each emitting a set of beams irradiating the corresponding photoreceptor with a predetermined distance therebetween along a sub-scanning direction; a deflection unit; a first optical system directing the sets of beams from the high-resolution light sources to the deflection unit; a low-resolution light source emitting a set of beams irradiating a predetermined photoreceptor with a distance therebetween larger than the predetermined distance along the sub-scanning direction; and a second optical system directing all of the sets of beams to the corresponding photoreceptor. The low-resolution light source and first optical system are positioned so as not to physically interfere with the high-resolution light sources and first optical system, and so as to allow the set of beams from the low-resolution light source to scan an image forming area on the predetermined photoreceptor along a main-scanning direction.
