Image forming apparatus

An image forming apparatus being capable of commonalizing a control signal for lighting of static eliminators, and controlling the static eliminators with a single port of CPU. The image forming apparatus includes a main body control part controlling image formation; a nip separation mechanism separating an intermediate transfer belt from color photosensitive drums; a separation control part driving nip separation mechanism on a separation control signal inputted from main body control part; a monochrome static eliminator comprised of a monochrome light guide body and a monochrome light source irradiating light on its end face; color static eliminators comprised of color light guide bodies and color light sources irradiating light on their end faces; and an irradiation location shifting mechanism shifting irradiation location of light emitted from color light source from end face of color light guide body when intermediate transfer belt is separated from color photosensitive drums.
