Abstract
To provide a technique to reduce force required for opening or closing a cover disposed in an image forming apparatus, the present invention provides a storage container that is attached to an open-close door in a state where the open-close door is open to expose inside of the image forming apparatus, and that is disposed in a predetermined attaching position in the image forming apparatus by closing of the open-close door. The storage container has an inlet for toner to enter, and a storage portion to store the toner. The inlet is opened in synchronization with operation of attaching the storage container to the open-close door, and the inlet is closed in synchronization with operation of detaching the storage container from the open-close door.

A storage container that can be attached to or detached from an image forming apparatus including an apparatus main unit and an open-close member that can open or close with respect to the apparatus main unit, the storage container comprising:
- a storage portion configured to store toner;
- an opening portion configured to move the toner between the storage portion and the apparatus main unit;
- and
- a shutter configured to open or close the opening portion,
- wherein the storage container can be attached to the open-close member in an opened state with respect to the apparatus main unit, and
- wherein the shutter opens the opening portion in synchronization with operation of attaching the storage container to the open-close member, and closes the opening portion in synchronization with operation of detaching the storage container from the open-close member.
A storage container that can be attached to or detached from an image forming apparatus including an apparatus main unit and an open-close member that can open or close with respect to the apparatus main unit, the storage container comprising:
- a storage portion that has a first opening portion and a second opening portion for toner to enter, and stores the toner;
- a first shutter that is disposed in the storage portion and opens the first opening portion in synchronization with operation of attaching the storage container to the open-close member;
- and
- a second shutter that is disposed in the storage portion, opens the second opening portion in synchronization with operation of closing the open-close member when the open-close member is closed after the first opening portion is opened by the first shutter, and closes the second opening portion in synchronization with the operation of opening the open-close member.
