PRIMARY COLOUR CARTRIDGE, DEVELOPER SUPPLY CARTRIDGE AND ELECTROPHOTOGRAPHIC IMAGE FORMING APPARATUS Russian patent published in 2016 - IPC G03G15/08 

FIELD: photography.

SUBSTANCE: disclosed process cartridge comprises electrophotographic photosensitive drum, developing roller for developing an electrostatic latent image formed on said electrophotographic photosensitive drum with help of developer, section of t developer of receiving side for developer, developer receiving hole for receiving developer in said section of developer of receiving side, valve section of receiving side, rotating between position for allowed reception of developer for opening said developer receiving hole and position of prohibited reception of developer for closing said developer receiving hole running section of the receiving side, rotating for an interrelated rotation of said section of gate of receiving side between position for allowed reception of developer and position of prohibited receiving the developer, wherein said rotation section of receiving side includes first working section of receiving side, which occupies working position when said valve section of receiving side is in developer prohibited reception position, and second working section of receiving side, which occupies working position when said valve section of receiving side is in position for allowed reception of developer, and control element, moving between position for control of rotation of said rotary section of receiving side and retracted position, displaced from position of control to allow rotation of said rotary section of receiving side, wherein when said control element occupies adjustment position and said first working section of receiving side occupies working position, said control element is engaged with said first working section of receiving side and when said control element occupies adjustment position and said second working section of receiving side occupies working position, said control element is engaged with said second working section of receiving side.

EFFECT: technical result consists in creation of primary colour cartridge with developer source, in which there is possibility of installation and removal of cartridge for supplying developer and primary colour cartridge in main assembly of imaging device independently from each other, without loss of developer, as well as preventing loss of developer through hole for feeding developer or through a hole for receiving developer.
