It is apparent that, in order for the detecting member to be driven, for a structure in which the detecting member and the power receiving member are located on different sides of the developing cartridge, it is necessary to mount a set of gears on both sides of the developing cartridge, respectively, and the mounting of these gears increases not only the material cost of the developing cartridge but also the assembly cost of the developing cartridge.

The shell 2 comprises a lower shell 21 and an upper shell 22 which are combined in the up-down direction, the lower shell 21 and the upper shell 22 enclose to form a cavity for containing carbon powder, and the carbon powder is supplied to the outside of the developing box under the combined action of a plurality of rotating pieces; the plurality of rotating members include a developing member 51 for conveying the toner to the outside, a toner feeding member 52 for conveying the toner to the developing member, and an agitating member 53 for agitating the toner, the developing member 51, the toner feeding member 52, and the agitating member 53 all rotating by receiving the driving force of the power receiving member 11; as shown in the drawing, the developing cartridge 1 further includes a transmission lever 54 rotatably mounted in the casing 2 for transmitting the driving force of the power receiving member 11 to the detecting member 6, and in the embodiment of the present invention, the detecting member 6 is coaxial with the transmission lever 54.
Further, the developing cartridge 1 further includes a gear train 7 disposed on the same side as the power receiving member 11, the gear train 7 being for transmitting the driving force to the transmission lever 54, and at the detection end, the detection member 6 is directly mounted on the transmission lever 54, and when the transmission lever 54 is driven, the detection member 6 is also driven to rotate about the rotation axis L2; the gear set 7 includes a first gear 71 coupled to the power receiving part 11, an intermediate gear 72, a third gear 73 coupled to the stirring member 53, and a fourth gear 74 coupled to the transfer lever 54, that is, the fourth gear 74 and the sensing member 6 are respectively located at both longitudinal ends of the transfer lever 54; wherein the intermediate gear 72 is meshed with the first gear 71 and the third gear 73, respectively, and at the same time, the third gear 73 is also meshed with the fourth gear 74, so that the driving force received by the power receiving member 11 is transmitted to the transmission lever 54 via the first gear 71, the intermediate gear 72, the third gear 73 and the fourth gear 74 in order, and the third gear 73 also drives the stirring member 53 to rotate about the rotation axis L1.
Preferably, the transmission rod 54 is disposed to extend in the upper housing 22 in the left-right direction, and more preferably, the transmission rod 54 passes through the upper housing 22 in the left-right direction, so that the mounting and dismounting of the fourth gear 74 and the detection member 6 are facilitated.
The rotation axis L2 is located above the rotation axis L1 in the up-down direction, so that the advantage of the design is that when the carbon powder contained in the housing 2 is large, the transmission rod 54 located above the stirring piece 53 does not cause too much obstruction to the flow of the carbon powder, and when the stirring blade 531 mounted on the stirring piece 53 rotates above the cavity along with the stirring piece 53, the stirring blade 531 interferes with the transmission rod 54, the carbon powder adhered on the stirring blade 531 is shaken off, and the carbon powder can be prevented from agglomerating at the stirring blade 531; the rotation axis L2 is located slightly behind the rotation axis L1 in the front-back direction, so that the influence of the transmission rod 54 on the fluidity of the toner can be further reduced, and the toner supply is smooth; as shown in fig. 3A and 3B, the transfer rod 54 has an overall cylindrical shape and a smooth outer surface, and thus, the influence of the transfer rod 54 on the flowability of the toner can be further reduced.

In fact, the developing cartridge 1 is operated in such a manner that not only the driving force but also the electric power needs to be received from the image forming apparatus, and the present invention relates to the developing cartridge 1 in which the electric power receiving member 8 for receiving the electric power is provided at the detecting end and the electric power receiving member 8 supplies the electric power received from the image forming apparatus to the developing member 51 and the powder feeding member 52 at the same time, which also contributes to the simplification of the structure of the developing cartridge 1, that is, the electric power receiving members do not need to be provided for the developing member 51 and the powder feeding member 52, respectively, and only one electric power receiving member 8 needs to be provided.
In another embodiment of the present invention, in terms of the stability of the force transmitted between the transmission rod 54 and the detection element 6 or the operation of the detection element 6, it is necessary to ensure that the detection element 6 and the transmission rod 54 are coaxial with each other in the embodiments where a member such as a delay device or a buffer device is provided between the detection element 6 and the transmission rod 54.
As described above, the detecting member 6 is provided coaxially with the transmission lever 54, and preferably, the detecting member 6 is directly mounted on one end of the transmission lever 54, and the detecting member 6 can be directly driven by the transmission lever 54 when the power receiving member 11 receives the external driving force, so that the detecting end where the detecting member 6 is located does not need to be mounted with power transmission members such as gears, belts, etc., but only needs to be mounted with the gear group 7 at the driving end, which design reduces the number of gears required for the developing cartridge 1, simplifies the structure of the developing cartridge 1, and finally, the cost of the developing cartridge 1 can be reduced.
