Zusammenfassung: | To collect waste toner with a simple and low-cost configuration.SOLUTION: An image forming apparatus comprises: an intermediate transfer belt 15B that revolves while holding toner; a blade 31 that is in contact with the intermediate transfer belt 15B; a waste toner container 33; and a guide member 34 that guides waste toner to the waste toner container 33. The guide member 34 includes: a receiving port 34A that receives waste toner scraped off from the intermediate transfer belt 15B by the blade 31; a discharge port 34B that is provided below the receiving port 34A, is smaller than the receiving port 34A, and is connected with the waste toner container 33; and a hollow part 34H that has a tapered shape from the receiving port 34A toward the discharge port 34B. The waste toner received in the receiving port 34A falls into the waste toner container 33 only by the gravity.SELECTED DRAWING: Figure 7
【課題】低コスト且つ簡潔な構成で廃トナーを回収することを目的とする。【解決手段】画像形成装置は 、トナーを保持して周回する中間転写ベルト15Bと、中間転写ベルト15Bに接触するブレード31と、廃トナー容器33と、廃トナーを廃トナー容器33に案内するガイド部材34と、を備え、ガイド部材34は、ブレード31によって中間転写ベルト15Bから掻き落とされた廃トナーを受け入れる受入口34Aと、受入口34Aの下方に設けられ、受入口34Aよりも小さく、廃トナー容器33に接続された排出口34Bと、受入口34Aから排出口34Bに向かってすぼまった形状の中空部34Hと、を備え、受入口34Aに受け入れられた廃トナーが重力のみによって廃トナー容器33に落下する。【選択図】図7 |
