Abstract
A cartridge is mountable in and dismountable from a main assembly of an image forming apparatus, in which the main assembly includes an opening and an openable member including a discriminating portion. The cartridge includes a process unit including a rotatable photosensitive member and a developing roller configured to supply toner to the photosensitive member, and a developer storage unit configured to store a developer. The developer storage unit is provided with a discharge opening for permitting discharge of the stored developer to the process unit and is mountable to and dismountable from the process unit. The developer storage unit is provided with a portion-to-be-discriminated provided so as to be engaged with the discriminating portion of the openable member when the cartridge is mounted in the main assembly and the openable member is in a closed position.
