ABSTRACT:
A toner recovery apparatus for an electrostatic copying machine comprises a toner container for receiving the toner recovered from the surface of a photosensitive drum, a toner supplying device for supplying the toner to a developing device, and a toner transfer mechanism for transferring the toner from the toner container to the toner supplying device. The toner transfer mechanism includes a duct having a supporting surface extending between the toner container and the toner supplying device, a ladder chain stretched on the supporting surface of the duct to define a series of toner support spaces, each space being formed by each link of the ladder chain and the supporting surface of the guide member, and driving means for driving the ladder chain, to transfer the toner supported by the toner support space, to the toner supplying device.
