Abstract
A cover 10 is provided to cover the opening of a toner container 2. The cover 10 is attachable to, and detachable from, the toner container 2. A valve element 12 capable of closing the opening 11 formed in the cover 10 is pressed up to an opening position by a pressing-up portion 20 provided on a developing apparatus side. Shifting of the valve element 12 to the opening position makes it possible to supply the toner from the toner container 2 to the developing apparatus.
