Abstract
In an image forming apparatus that includes a collection container for collected toner, the collection container is not easily pushed back by a reaction force against a closing force of a shutter provided in a feeding portion for the collected toner. A spiral rib guides a contact rib to move the sealing shutter in a direction of opening a transfer opening against an urging force of a twisted coil spring in the process of connecting a collected toner box to a feeding pipe. A low reaction force area guides the contact rib after the spiral rib in the process of connecting the collected toner box to the feeding pipe. An inclination angle of the low reaction force area relative to the direction of connecting the collected toner box is less than an inclination angle of the spiral rib relative to the direction of connection of the collected toner box.
