置。[Scope of Claim for Utility Model Registration] In an image forming apparatus configured to form a color toner image by irradiating a single laser beam with a plurality of developing devices arranged around a photosensitive drum, An exposed part is placed by a laser beam at a position corresponding to the developing device, and the means for changing the exposed part is performed by changing the reflection position by a mirror placed in the optical path, and the exposed part is placed at a position closest to the transfer part. A developing device containing black toner is stored in the developing device, and the first copy is formed by irradiating a laser beam onto an exposure portion corresponding to the developing device located closest to the transfer portion. Exposure device in an image forming apparatus.
