Claims

[Claims for Utility Model Registration] (1) A developer is stored in the interior, and has a developer discharge opening for allowing the stored developer to fall into the developer supply section, and the interior is normally used. A developer cartridge for an image forming apparatus is provided with a sealing member that closes an opening and opens the opening by being rolled up. (2) The developer is stored inside and has a developer discharge opening for dropping the stored developer into the developer supply section, and the opening is normally sealed and the developer is wound up. A developer cartridge for an image forming apparatus, which is provided with a seal member that opens the opening when the cartridge is loaded, and includes means for automatically winding up the seal member when or after loading the cartridge. (3) One of the components of the developer cartridge is broken, deformed, or moved by loading the developer cartridge, and this is detected;
3. A developer cartridge for an image forming apparatus according to claim 1 or 2, wherein said cartridge is not reusable.
