The counting mechanism 35 includes a bevel gear portion 36 and a detected portion 37, and the detected portion 37 can trigger the detecting portion 9 of the electronic imaging device under the driving of the bevel gear portion 36, so that the electronic imaging device can identify the developing cartridge.

The second gear 34 is a bevel gear, and one end of the counting mechanism 35 near the second gear 34 is provided with a bevel gear portion 36 for receiving a driving force from the second gear 34. The conductive posts 38 constrain the counting mechanism 35 such that the counting mechanism 35 rotates along an axis of rotation that is not parallel to the first direction. The counting mechanism 35 is further provided with a detection target 37 on the side close to the detection unit 9. The cylinder that constrains the counting mechanism in this embodiment may not be made of a conductive material, i.e., the non-conductive cylinder constrains the counting mechanism 35.

In a specific implementation, the developing cartridge of this embodiment is installed in an electronic imaging device, and the driving gear 210 receives the driving force transmitted by the electronic imaging device and transmits the driving force to the counting mechanism 35 through the first gear 221, the stirring element 13 and the second gear 34 in sequence, so as to drive the detected portion 37 to move and touch the detecting portion 9 of the electronic imaging device, and further enable the electronic imaging device to recognize the developing cartridge.
