Patent ID: 11579545

Abstract:
A toner container includes a toner discharge port and a shutter to open and close the toner discharge port. The shutter includes a shutter main portion and shutter deforming portions. Each of the shutter deforming portions includes a stopper and a stopper releaser. The stopper contacts a contact portion of the toner container to restrict a movement of the shutter in an opening direction. The stopper releaser receives an external force from below to displace the stopper upward to release a contact state of the stopper with the contact portion. The stopper releaser of one of the shutter deforming portions releases the contact state with the contact portion independently of another of the shutter deforming portions. When the contact state of the stopper with the contact portion is released in all of the shutter deforming portions, restriction of the movement of the shutter in the opening direction is released.
