Abstract
An image forming apparatus that has an image bearing member to be removably mounted to the image forming apparatus includes an intermediate transfer member, a toner detection unit, an exposure device, a forming unit, and a judgment unit. The judgment unit judges a mounting state of the image bearing member based on whether the toner detection unit detects a toner image transferred on a surface of the intermediate transfer member. When the image bearing member is mounted, first and second patterns of toner images are formed apart by a predetermined interval in a rotation direction of the intermediate transfer member. Where the toner detection unit detects the first and second patterns of toner images, the judgment unit judges that the image bearing member is mounted. Where one of the first and second patterns is not detected, the judgment unit judges that the image bearing member is not mounted.
