Claim Text:
1. An image forming apparatus comprising: a photosensitive member; an exposure unit configured to expose the photosensitive member to light to form an electrostatic latent image on the photosensitive member; a developing unit configured to develop the electrostatic latent image formed on the photosensitive member by the exposure unit, with toner; a mounting unit configured to mount a container containing toner; a mounting detection unit configured to detect that the container is mounted on the mounting unit; a driving unit configured to rotate the container mounted on the mounting unit to replenish the developing unit with the toner from the container; a rotation detection unit configured to detect rotation information associated with the container rotated by the driving unit; and a controller configured to control the driving unit such that a rotation speed of the container coincides with a predetermined speed, based on the rotation information detected by the rotation detection unit, wherein the controller is configured to, if the mounting detection unit detects that the container is mounted on the mounting unit, not control the driving unit based on the rotation information until replenishment condition of the container mounted on the mounting unit satisfies a predetermined condition, wherein the mounting detection unit includes an acquisition unit configured to obtain tag information associated with a tag attached to the container, and wherein the mounting detection unit is configured to, if the tag information obtained by the acquisition unit is different from previously stored predetermined information associated with a tag, detect that the container is mounted on the mounting unit, and wherein the mounting detection unit is configured to, if the acquisition unit fails to obtain the tag information, detect that the container is mounted the mounting unit.
