ABSTRACT:
A cartridge is detachably mountable to a main assembly of an electrophotographic image forming apparatus. The cartridge includes a developer accommodating portion, a developer supply port supplying the developer to a developing device for developing an electrostatic latent image formed on an electrophotographic photosensitive member, a removable sealing tape sealing the developer supply port, and a covering member taking an opening position for opening the port and a closing position for closing the port and to which one longitudinal end of the tape is fixed, the covering member being effective to cover the tape sealing the port when it is at the closing position, and cartridge locking portion for locking the covering member at the closing position. When the cartridge is mounted to the main assembly of the apparatus, locking between the cartridge locking portion and the covering member is released by engagement between the covering member and the main assembly, and the covering member moves from the closing to the opening position, and the tape is removed from the port to open the port.
