  • Publication number: 20200004177
    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.

  • Publication number: 20190339634
    Abstract: Conventionally, when a developer is supplied into a developer receiving apparatus from a developer supply container using the air, a filter is provided in the developer receiving apparatus side, but the pressure feeding type wherein a mixture of the air and the developer is continuously fed from the developer supply container into the developer receiving apparatus side involves a problem of filter clogging. The developer supply container side is provided with a pump portion which effects a suction operation for moving the air from inside of the developer receiving portion to the developer accommodating portion side and a discharging operation for moving the air from the inside of the developer accommodating portion to the developer receiving portion side. By this, a back washing effect of dusting the developer from the filter is applied to the filter portion during the suction operation, so that the clogging of the filter is suppressed.
