Abstract
The present invention relates to a processing cartridge, comprising a developing unit and a photosensitive unit, of which the latter consists of a photosensitive member and a developer chamber and has a developer outlet connecting the chamber and a sealing cap matching the developer outlet and used to seal the said outlet. Based on the said technical proposal, the photosensitive unit is designed with a developer outlet connecting the chamber and with a sealing cap matching the developer outlet and used to seal the said outlet, so, when the photosensitive unit becomes full with developer, the sealing cap can be opened to remove the developer in the photosensitive unit, which facilitates the cleaning without affecting the normal operation of the processing cartridge.
