  • Patent number: 11016414
    Abstract: An image forming apparatus includes a toner container and an apparatus main body. The toner container contains a toner. To the apparatus main body, the toner container is attached in a detachable manner. The toner container includes a container main body and a shutter. The container main body has a toner discharge port. The shutter is rotatable between a close position where the shutter closes the toner discharge port and an open position where the shutter opens the toner discharge port. The apparatus main body includes a driving source and a connection mechanism connectable the driving source to the shutter. When the driving source is driven in a state where the connection mechanism connects the driving source to the shutter, a driving force of the driving source is transmitted to the shutter via the connection mechanism, and the shutter is rotated from the close position to the open position.

  • Patent number: 10948849
    Abstract: Conventionally, the developer in the developer supply container is discharged by an air-supply pump and a suction pump which are provided in the main assembly side of the image forming apparatus, and therefore, the developer is compacted by the increase of the internal pressure of the developer supply container resulting from the air-supply. Therefore, the proper suction of the developer from the developer supply container becomes difficult with the result of shortage of the developer amount to be supplied. A bellow-like pump is provided on the side of the developer supply container, and the pump alternately repeats the suction operation and the discharging operation through the discharge opening by a driving force inputted from the image forming apparatus side. By this, the developer can be sufficiently loosened, thus properly discharging the developer.
