  • FIG. 17 is a schematic diagram illustrating a switch member and a corresponding switch member mounting portion on the toner cartridge according to Embodiment 2. Unless specifically stated otherwise, other parts of the toner cartridge have identical structures as in Embodiment 1.
  • the switch member 450 includes a main body 455 that is connected to the switch member mounting portion 470 by a connection member 460.
  • the main body 455 may rotate freely around the connection member 460 in a plane in which the switch member mounting portion 470 is located.
  • a torsion spring 480 is mounted to the connection member 460, with one end abutting against a block portion 451 on the main body of the switch member 455 and then other end abutting against the case of the toner cartridge.
  • the main body 455 is provided with a guide groove 452, and the switch member mounting portion 470 is provided with a guide post 472 matched with the guide groove 452, where the guide groove 452 and the guide post 472 are positioned along the direction in which the torsion spring 480 applies an elastic force to the main body 455.
  • the main body 455 is further provided with a force bearing portion 454 and a central opening 453.
  • the torsion spring 480 applies a force to the switch member 450 by the block portion 451, the force driving the central opening 453 away from the toner outlet 471, so that the central opening 453 and the toner outlet 471 keep staggered, thereby enabling the switch member 450 to cover the toner outlet.
  • the toner is enclosed within the toner cartridge.
  • the guide post 472 abuts against a blind end of the guide groove 452, playing a role of limiting the switch member 450.
  • the force bearing portion 454 of the switch member 450 abuts against the edge 189 of the image forming device, so that the switch member 450 initially keep stationary relative to the toner inlet 188, and the central opening 453 of the switch member 450 is initially aligned with the toner inlet 188 of the image forming device 180.
  • the toner outlet 471 slides towards the central opening 453 and the toner inlet 188, and the three openings (i.e. the toner outlet 471, the central opening 453 and the toner inlet 188) are made to be aligned. At this time, the toner may flow into the toner inlet 188 through the toner outlet 471 and the central opening 453.
  • the central opening of the switch member may also be removed, which accordingly reduces the area occupied by the main body of the switch member.
  • the torsion spring may also be replaced with a tension spring.
  • one end of the tension spring is connected with the switch member, and the other end with the main body of the toner cartridge.
  • the blocking rate of the switch member is presumed to be “1” when the toner outlet is completely blocked by the switch member, and the blocking rate is “0” when the toner outlet is not covered by the switch member at all; the throughput of the toner is “1” when the toner outlet is perfectly aligned with the toner inlet, and the throughput is "0” when the toner outlet is not aligned with the toner inlet at all.
  • the blocking rate of the switch member on the toner outlet and the throughput rate of the toner between the toner outlet and the toner inlet will change as follows:
  • the toner cartridge In third stage, the toner cartridge is fully mounted in place, and at this time, the blocking rate of the switch member on the toner outlet becomes "0", and the throughput between the toner outlet and the toner inlet becomes "1".
  • the blocking rate of the switch member on the toner outlet and the throughput between the toner outlet and the toner inlet will change contrarily to those in the above stages, and thus will not be repeated herein.
  • the switch member firstly keeps stationary relative to the toner outlet and the toner inlet, and then the toner outlet slides or rotates relative to the switch member until the toner outlet communicates with the toner inlet, which dramatically alleviates the technical problem of toner leakage when the switch member for the toner outlet of the toner cartridge is being opened.
