Zusammenfassung: | To solve the aggregation of toner near a toner discharge port in a toner cartridge.SOLUTION: A toner cartridge 1 has a toner conveying screw 54 in a toner storage container 40. The toner conveying screw 54 is provided movably along an axial direction, includes an urging member 66 at one end, and includes a toner stirring member 60 at the other end. When the toner conveying screw 54 is moved by the urging member 66 toward the other end, the toner stirring member 60 is arranged separate from a toner discharge port 52, and when the toner conveying screw 54 moves toward one end against the urging force, the toner stirring member 60 is arranged in proximity to the toner discharge port 52.SELECTED DRAWING: Figure 2
【課題】トナーカートリッジにおけるトナー排出口近傍でのトナーの凝集を解消する。【解決手段】トナーカートリッジ1は、トナー収容容器40内にトナー搬送スクリュー54を有する。トナー搬送スクリュー54は軸線方向に沿って移動可能に設けられ、一端部に付勢部材66を備え、他端部にトナー撹拌部材60を備えている。付勢部材66によってトナー搬送スクリュー54が前記他端部側に移動しているとき前記トナー撹拌部材60はトナー排出口52から離れて配置され、付勢力に抗してトナー搬送スクリュー54が前記一端部側に移動すると、トナー撹拌部材60はトナー排出口52に近接して配置される。【選択図】図2 |
