The invention discloses an image forming apparatus. The image forming apparatus includes a plurality of image forming units that charge a surface of a photoconductor to form an image, a static eliminator that outputs static elimination light to eliminate a charge remaining on the photoconductor after image formation by the image forming unit, and a controller that controls the image forming unit and the static eliminator. The static eliminator includes a light source that emits the static elimination light, a light guide unit that guides the static elimination light from the light source to the photoconductors, and outputs the guided static elimination light to surface of the photoconductors, and a light shield unit provided inside the light guide unit, or between the light guide unit and the photoconductors in an optical path between the light source and the surface of each of the photoconductors, and configured to transmit or block the static elimination light. So static elimination of a plurality of photoreceptors can be performed only through utilization of the single light source, the static elimination light cannot reach unused photoreceptors when single color printing is performed, and the light fatigue of the unused photoreceptors is prevented.
