Conventionally, a developer in a developer replenishing container is discharged by an air supply pump and a suction pump which are provided in the body of an image forming device, and thus the developer is compressed by an increase in the pressure in the developer replenishing container caused by the air supply. Consequently, it becomes difficult to properly suck the developer from the developer replenishing container, thereby causing an insufficient amount of developer to be replenished. Thus, a bellows pump is provided in the developer replenishing container, and the pump is configured to alternately and repeatedly switch between an air suction operation and an air discharge operation via a discharge port by drive force inputted from the image forming device. Therefore, the developer can be fully decomposed and can be properly discharged. |
