Abstract: An image forming apparatus includes: an image carrier; a development unit for forming a toner image on the image carrier by supplying a toner contained in a developer reservoir to a latent image formed on the image carrier by means of a developer carrier; a transfer unit for transferring the toner image formed on the image carrier onto a transfer medium; a recovery unit for recovering the toner remaining on the image carrier after image transfer; a return unit for transporting the recover toner recovered by the recovery unit so as to return the recover toner into the developer reservoir of the development unit; and a separator/feeder for separating the toner contained in the developer reservoir from the recover toner thereby exclusively feeding the toner contained in the developer reservoir to the latent image formed on the image carrier by means of the developer carrier.

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.
