  • the fourteenth abutting surface 246 in this embodiment functions similarly to the fourteenth abutting surface 146 in the first embodiment, but is compared with the fourteenth abutting surface 146 in the first embodiment.
  • An annular projection is provided around the fourteenth abutting surface 246 to prevent the deflection of the elastic member during production assembly from affecting the production efficiency.
  • the second movable portion 240b includes the support block 241, and the support block 241 extends in the direction away from the powder cylinder.
  • the imaginary circle surrounded by the contact end 241b is smaller than the radius of the circle surrounded by the support block 241, that is, the distance between the contact end 241b and the rotation axis of the power receiving member is smaller than the distance between the support block 241 and the rotation axis of the power receiving member. Therefore, the further the guide surface 241a is away from the direction of the powder cylinder, the smaller the distance from the rotation axis of the power receiving member.
  • Such a design makes it possible for the second movable portion 241b to better abut against the rotational driving force transmitting member of the image forming apparatus during the mounting of the toner cartridge onto the image forming apparatus, preventing the image forming apparatus from being worn due to the long use time.
  • the rotating shaft of the power receiving member ie, the rotating shaft of the toner cartridge, the two are coaxial
  • the rotating shaft of the rotational driving force transmitting member on the image forming apparatus are not coaxial, causing a collision when the toner cartridge is mounted, causing the image to be formed. The normal operation of the device.
  • the power receiving member in the embodiment deletes the limiting protrusion, and directly uses the transmission rod 226 to pass through the transmission hole 133 and the transmission hole.
  • the hole wall of 133 abuts as shown in FIG. This can reduce component structural complexity and reduce costs.
  • the blocking portion 132 may not be disposed on the stopper 130.
  • the stopper 130 provided with the blocking portion 132 in the first embodiment can also be fully applied to the power receiving component in the embodiment, but the blocking portion 132 no longer functions, so that the materials are universally used to save the number of mold opening times and reduce the cost. .
  • the hollow protrusion 1241 is no longer provided to constrain the rod 150, and only the rod 150 is installed inside the structure enclosed by the fixing rod 222.
  • the fixing rods 222 of the embodiment support the driving teeth 121.
  • the fixing rods 222 in this embodiment are disposed in four, and two of the fixing rods 222 that are axially symmetrical with respect to the power receiving member are provided with driving teeth. 221a, the other two fixing rods 222 about the axis of rotation of the power receiving member are not provided with driving teeth 221a, as shown in FIG.
  • the wiring of the two fixing rods 222 provided with the driving teeth 221a is orthogonal to the wiring of the two fixing rods 222 where the driving teeth 221a are not provided.
  • other numbers of fixing rods 222 and driving teeth 221a may be provided, but at least two fixing rods 222 including driving teeth 221a should be included.
  • a stopper tooth 221b for preventing the second movable portion 240a from coming out is further provided on the fixing rod 222.
  • the limiting teeth 221b may also be disposed only on the partial fixing rods 222, but at least two of the fixing rods 222 may include the limiting teeth 221b.
  • the limiting teeth 221b do not participate in the work, and the only function of the limiting teeth 221b in this embodiment is to prevent the second movable portion 240a from coming out.
  • the fewer driving teeth in this embodiment can make the meshing process smoother, and further reduce the meshing difficulty caused by the interference between the driving teeth and the image forming apparatus.
  • the power receiving component and the powder cartridge provided by the embodiments of the present application can prevent the driving tooth structure of the powder cartridge in the prior art from being locked with the internal meshing portion of the image forming apparatus, and also reduce the possibility of error in the operation of the machine, and improve the self-sealing. Sex, which effectively prevents the developer in the toner cartridge from leaking, and pollutes the environment and affects the image quality.
