PURPOSE: To prevent formation of bridge by the developer on a discharging end part of an auger, by disposing an anti-bridging device including a flexible paddle wheel fitted to the auger shaft. CONSTITUTION: The anti-bridging device includes the paddle wheel 78 fixedly fitted to a slot 79 in the shaft 76 of the first developer transferring auger 37. The length of this flexible paddle wheel 78 is made larger than a diameter of a container tube 38, and both end parts of the paddle wheel 78 is made longer than a radial value of the inside diameter of the container tube 38. Thus, both ends of the paddle wheel 78 is severally made so as to be present on the extended downstream side in the space between the discharge end part by the developer auger and the take out auger 41, therefor it is assured that the bridge formation by the developer is prevented. |
