Zusammenfassung: | PROBLEM TO BE SOLVED: To provide a waste toner storage container that can store, as efficiently as possible, a waste toner that is no longer necessary for image formation.SOLUTION: A waste toner storage container 9 is provided therein with a partition wall 101 that partitions a space above a conveying screw 122. A notch part through which the conveying screw 122 is inserted is provided below the partition wall 101, and a height position of a lower end of the partition wall 101 from a bottom plate 96 is the same as that of a lower end of the conveying screw 122. A waste toner dropped from a waste toner receiving port 131 and accumulated in a first lower space 161 is conveyed to a storage space 172 by the conveying screw 122 in a conveyance direction α via the partition wall 101. When a height of accumulation of waste toner Ta deposited in the storage space 172 becomes higher than that of the conveying screw 122, backflow of the waste toner from the storage space 172 to the first lower space 161 is regulated by the partition wall 101.SELECTED DRAWING: Figure 9
【課題】画像形成に不要になった廃トナーをできるだけ効率よく収容可能な廃トナー収容容器を提供すること。【解決手段】廃トナー収容容器9の内部において搬送スクリュー122よりも上の空間を仕切る隔壁101が設けられている。隔壁101の下側には、搬送スクリュー122が挿通される切り欠き部が設けられており、隔壁101の下端の、底面板96からの高さ位置が搬送スクリュー122の下端と同じになっている。廃トナー受入口131から落下して第1下部空間161に蓄積された廃トナーは、搬送スクリュー122により搬送方向αに隔壁101を介して収容空間172に搬送される。収容空間172に堆積された廃トナーの山Taの高さが搬送スクリュー122よりも高くなると、隔壁101により収容空間172から第1下部空間161への廃トナーの逆流が規制される。【選択図】図9 |
