Embodiment 1
[0035] In this embodiment, a developing cartridge is provided. The developing cartridge can be applied to commonly used electrophotographic imaging devices such as printers, copiers and facsimile machines, and the overall structure of the developing cartridge is consistent with Figure 1 to Figure 3 The overall structure of the developing cartridge in is similar, so if there is no special instruction, the overall structure of the developing cartridge in this embodiment is the same as figure 1 the same or similar in . The developing cartridge of this embodiment specifically includes a powder bin for accommodating the developer, and also includes a counting mechanism and a transmission gear for transmitting power to the counting mechanism. The counting mechanism includes a first rotating member and a second rotating member.
[0036] Wherein, the transmission gear can at least mesh with one of the first rotating member and the second rotating member to transmit power to the count...
Embodiment 2
[0061] On the basis of the first embodiment above, the first rotating member can also be configured as a full-toothed gear structure, and the first rotating member and the second rotating member are not coaxially connected, but meshed with each other. Figure 7a It is a schematic diagram of the structure of the counting mechanism in the developing cartridge in the initial position provided by the second embodiment of the present invention. Figure 7b It is a schematic diagram of the structure of the counting mechanism in the developing cartridge in the final position provided by the second embodiment of the present invention. Such as Figure 7a and Figure 7b As shown, in this embodiment, the first rotating member 111 can be set as a full-toothed gear, and the second rotating member 112 can be a tooth-less gear, and the first rotating member 111 and the second rotating member 112 mesh, and the second rotating member 112 and The transmission gear 25 is engaged.
