1. An image forming apparatus comprising a monochrome image forming part that forms a toner image for a monochrome image on a monochrome photosensitive drum; color image forming parts that form toner images for color images on color photosensitive drums; and an intermediate transfer belt that once carries the toner image to be transferred to a recording paper, the image forming apparatus, at the time of monochrome printing, transferring only the toner image that has been formed on the monochrome photosensitive drum, to the intermediate transfer belt, and at the time of color printing, sequentially transferring the toner image that has been formed on the monochrome photosensitive drum, and the toner images that have been formed on the color photosensitive drums, to the intermediate transfer belt,
the image forming apparatus including: a main body control part that controls image formation with the monochrome image forming part and the color image forming parts, a nip separation mechanism that separates the intermediate transfer belt from the color photosensitive drums, a separation control part that drives the nip separation mechanism on the basis of a separation control signal that is inputted from the main body control part, a monochrome static eliminator that is comprised of a monochrome light guide body that extends in a rod shape along the monochrome photosensitive drum, and a monochrome light source that irradiates light on an end face of the monochrome light guide body, color static eliminators that are comprised of color light guide bodies that extend in a rod shape along the color photosensitive drums, and color light sources that irradiate light on end faces of the color light guide bodies, and an irradiation location shifting mechanism that shifts the irradiation locations of the light that is emitted from the color light sources, from the end faces of the color light guide bodies, in a state of the intermediate transfer belt being separated from the color photosensitive drums. |
