Entwicklernachfüllkassette und Entwicklerempfanggerät in dem diese Kassette montiert ist

摘要

A developer supply opening of a developer replenishing cartridge is sealed by a flexible film peelably adhered to the cartridge, and one end of a folded back portion of the film is secured to a gripper which is manipulated by an operator and which is separably mounted on the cartridge. A developer receiving container on which the cartridge can be mounted has a lid. When the lid is opened, the lid engages by the gripper to separate the latter from the cartridge.
