Abstract
A waste toner collecting apparatus of the present invention reliably prevents waste toner from spilling when replacing the waste toner box by opening the front cover of an image forming apparatus as the first through fifth shutters close the respective waste toner conveyance end sections. The first through fifth shutters are locked when no waste toner box is mounted in the image forming apparatus. The first through fifth shutters are unlocked when a waste toner box is mounted in the image forming apparatus. It can reliably prevent an operation error of operating the image forming section with the waste toner conveyance end sections left in an open state as the stay of the cover presses the first through fifth shutters when a waste toner box is not mounted.
