Abstract:
In a developing apparatus, a housing has a first opening. A shutter is movable between an open position and a closed position. A locking member is movable between a lock position and a release position. The locking member is located between the housing and the shutter in a cartridge-attachment direction. The locking member is located at the lock position in a case where the toner cartridge is detached from the developing apparatus. The locking member is in contact with the toner cartridge, thereby moving from the lock position to the release position in a case where the toner cartridge is attached to the developing apparatus. A cover having a second opening that is in communication with the first opening in a state where the shutter is at the open position is located at an opposite side of the locking member with respect to the shutter in the cartridge-attachment direction.

Claim (Index 1):
A developing apparatus, to which a toner cartridge is attachable, the developing apparatus comprising:\n a developing roller rotatable about a first axis extending in a first direction; a housing configured to accommodate toner therein, the housing having a first opening; a shutter being movable relative to the housing between an open position, at which the shutter opens the first opening, and a closed position, at which the shutter closes the first opening; a first lock lever being movable relative to the housing between a first lock position, at which the first lock lever locks the shutter in a case where the shutter is at the closed position, and a first release position, at which the first lock lever releases the shutter in a case where the shutter is at the closed position; a second lock lever being movable relative to the housing between a second lock position, at which the second lock lever locks the shutter in a case where the shutter is at the closed position, and a second release position, at which the second lock lever releases the shutter in a case where the shutter is at the closed position; and a seal member being positioned between the first lock lever and the second lock lever in the first direction, wherein the first lock lever being movable to the first release position from the first lock position and the second lock lever being movable to the second release position from the second lock position in response to movement of attaching the toner cartridge to the developing apparatus.
