  • the end cover 480 may be further provided with a first end wall 442 and a second end wall 443, such that the movable element 430 may be located between the first end wall 442 and the inner wall 482, and the second end 460b of the elastic element 460 may be located between the second end wall 443 and the inner wall 482, thereby preventing the movable element 430 and the elastic element 460 from being detached from the end cover 480 during the movement.
  • the movable element 430 may be disposed not only on the end cover 480, but also on the protective cover 500 or the waste toner container 300, as long as the movable element 430 may transmit the received pushing force, which is provided by the electronic image-forming device, to the toner container 400 of the processing cartridge, thereby enabling the relative movement between the toner container 400 and the waste toner container 300.
  • the processing cartridge may also include an elastic element 260, which is located between the frame of the toner container 200 and the movable element 230, and the elastic element 260 may provide a pushing constraint on the movable element 230 during the movement of the movable element 230 to help the movable element be restored.
  • the elastic element 260 may be disposed in the accommodation container 240. One end of the elastic element 260 may be abutted against the movable element B230, and the other end may be abutted against the frame of the processing cartridge.
  • the elastic element 260 When the elastic element 260 is in a natural state, one end of the elastic element 260 may only touch the movable element 230, and no force may be exerted on the movable element 230 or a force directed to the outside of the processing cartridge may be exerted on the movable element 230.
  • the elastic element 260 may be a sponge, which may be respectively abutted against two abutting portions 233 of the movable element 230.
  • the movable element 230 When the processing cartridge is installed in the electronic image-forming device and the abutting surface 231 of the movable element 230 is abutted against the inside of the electronic image-forming device, especially against the protrusion inside the electronic image-forming device, the movable element 230 may be retracted inside the processing cartridge.
  • the resistance generated by the relative movement may be small; and the gravity of the movable element 230 may be sufficiently small, or the pushing force exerted by the elastic element 260 on the movable element 230 may be sufficiently small when the elastic element 260 is disposed, such that, at this point, the movable element 230 may not push the protrusion downwardly and may not make the protrusion be retracted downwardly. At this point, the movable element 230 may be in the first position.
  • the internal movement of the electronic image-forming device may make the protrusion move along the direction opposite to the processing cartridge installation direction, and the protrusion may move away from the position being abutted against the abutting surface 231 and move to the side close to the pushing surface 232.
  • the movable element 230 may be subjected to the action of gravity and the elastic restoring force of the elastic element 260 to extend out downwardly, thereby implementing the restoring operation.
  • the movable element 230 may be in the second position. In the second position, the force exerted by the elastic element 260 on the movable element 230 may be reduced or till the elastic element 260 restores to the above-mentioned natural state.
  • the protrusion may exert a force on the pushing surface 232 and push the toner container to move relative to the waste toner container, thereby implementing the roller drum separation.
  • the elastic element 260 may be a single piece sponge which is located in the accommodating container 240 and directly abutted against two abutting portions 233 of the movable element 230.
  • the remaining structures may be same as those in exemplary embodiment one. In one embodiment, it may ensure that the moving operation of the movable element 230 after each installation may be executed steady; and during the movement between the first position and the second position, the movable element 230 may be provided with a stable restoration.
