The invention provides an electrophotographic image forming apparatus. The apparatus includes first and second photosensitive bodies, first and second exposing units to form electrostatic latent images on the first and second photosensitive bodies respectively charged to a uniform electric potential, a first developing unit to develop an electrostatic latent image of the first photosensitive body by supplying a transparent toner to the electrostatic latent image of the first photosensitive body, a second developing unit to develop an electrostatic latent image of the second photosensitive body by supplying a color toner to the electrostatic latent image of the second photosensitive body, a first cleaning member to eliminate a toner that remains on the second photosensitive body, wherein the first developing unit is a mono-component cleanerless developing unit, and wherein a transparent toner which remains on a non-image portion of the first photosensitive body is reclaimed to the first developing unit by a difference between a surface electric potential of the first photosensitive body and an electric potential of a developing bias voltage applied to a first developing unit.
