Abstract:
1. An electro photographic image forming apparatus comprising: first and second photosensitive bodies; first and second exposing units to form electrostatic latent images on the first and second photosensitive bodies each of which being charged to a predetermined electric potential; a first developing unit to develop the electrostatic latent image on the first photosensitive body by supplying a transparent toner thereto; and a second developing unit to develop the electrostatic latent image on the second photosensitive body by supplying color toners thereto, wherein the first developing unit is a developing unit employing a two-component developer as the transparent toner comprising a magnetic carrier and a transparent toner material, and the second developing unit is a developing unit employing a mono-component developer, wherein: the second photosensitive body comprises a plurality of the second photosensitive bodies; and the second developing unit comprises a plurality of the second developing units to develop corresponding ones of the electrostatic latent images on the second photosensitive bodies by supplying different color toners comprising black toner, yellow toner, magenta toner, and cyan toner, thereto.
