特徴とする画像形成装置。[Scope of Claim for Utility Model Registration] A process unit having a cleaning section for removing residual toner from a photoreceptor, and a container for storing toner discharged from the cleaning section of the process unit are configured to be detachably attached to the main body of the apparatus. In the image forming apparatus, a protrusion into which the toner enters is formed in the container;
The device body detects toner that has entered the protrusion to determine whether the attached container is new or old, and is normally biased upward to prevent the container and process unit from being attached. An image forming apparatus according to the present invention, further comprising a sensor that detects attachment of the container and the process unit by vertical movement of a biasing member that is pushed downward.
