Abstract
In an image forming apparatus, a cleaning device removes toner remaining after image formation. A toner storing section stores the toner collected by the cleaning device. A toner transferring device transfers the toner from the cleaning device and implemented by a powder pump. The powder pump includes a screw pump rotatable to move the toner in its axial direction, and an air feeding arrangement for causing the toner being moved by the screw pump to flow in a dispersed state. The toner transferring device and toner storing section are communicated by a path constituted by a flexible material.
