PROCESSING CARTRIDGE

摘要

A processing cartridge (1) comprising a drum unit (2) and a development unit (3). The drum unit (2) comprises a first housing. The development unit comprises a second housing (31). The second housing (31) encircles to form a toner powder cavity. A development roller (32) is mounted at an outlet of the toner powder cavity. The second housing (31) is provided with a spring mounting position (39). A spring (38) mounted at the spring mounting position (39) is abutted between the first housing and the second housing (31). A drive-side pivot (71) is provided on a drive-side frame (7). The drive-side pivot (71) is arranged on a line (L1) between the axial projection of the development roller (32) on the drive-side frame (7) and the axial projection of the spring mounting position (39) on the drive-side frame (7). A driven-side pivot (61) is provided on a driven-side frame (6). The driven-side pivot (61) and the drive-side pivot (71) are coaxially arranged. A drive-side lateral cover (5) is provided with a first pivot mounting position (53) on a position corresponding to the drive-side pivot (71). An arced slide groove (52) is provided through the drive-side lateral cover (5) at a position corresponding to a driver component (27) driving the development roller (32).
