ABSTRACT:
A toner recovery device, capable of preventing toner from spilling out of the space between protruding sections and an inner wall of a toner-conveying pipe, and process cartridge and image forming apparatus having this device. Residual toner after transfer, which is carried into a carry-in section of the toner-conveying pipe, is held by the protruding sections of a toner-conveying belt and a bottom surface of the toner-conveying pipe, and conveyed to a carry-out section. Accordingly, the residual toner after transfer can be prevented from oscillating while being conveyed to the carry-out section. Therefore, the residual toner after transfer is prevented from spilling out of the space between the protruding sections and the inner wall of the toner-conveying pipe, and the amount of residual toner after transfer to be conveyed to the carry-out section can be prevented from being reduced.
