The tone conveyance has a conveyance pipe whose base end portion is rotatably connected to the cleaning device and tip end portion with an outlet opening is detachably coupled to an inlet opening of the recovery toner container so that the tip end portion is pivotted around the base end portion so as to take the coupled position and the detached position. The operating lever is linked to the conveying pipe for pivotting the tip end portion between the coupled position and the detached position. The shutter is adapted to move on the conveying pipe interlockingly with the movement of the operating lever so that the shutter closes the outlet opening of the conveying pipe on the detached position and opens the outlet opening on the coupled position.
