[0022] A developing roller positioning side plate 13 is provided inside the powder bin main body 1 and at one end close to the gear side cover 2, and a driving slot 131 is provided on the developing roller positioning side plate 13. The developing roller positioning structure 21 of the gear side cover 2 is partially embedded in the driving slot 131, and the remaining part of the driving slot 131 is embedded in a sealing shaft ring 132. The other end of the developing roller passes through the sealing shaft ring 132 and the gear side cover 2, and cooperates with the axis of the developing roller driving gear 41 installed on the gear end cover 4 on the outer edge of the gear side cover 2.

[0023] A powder filling port 14 is further provided at one end of the powder bin body 1 close to the conductive side cover 3 , and the conductive side cover 3 covers the powder filling port 14 .

[0024] A conductive outer cover 5 is positioned outside the conductive side cover 3 , and the conductive outer cover 5 is used to locate the distance between the powder bin body 1 and the waste powder bin of the toner box.

[0025] Installation positioning posts 15 are provided on both sides of the top of the powder bin body 1 , and the installation positioning posts 15 are used to match the installation position between the powder bin body 1 and the waste powder bin of the toner box.

[0026] In summary, the specific implementation of the utility model is as follows: the powder bin body 1 is made of a light and durable material, and a gear side cover 2 and a conductive side cover 3 are installed at both ends respectively. At one end close to the conductive side cover 3, a developing roller arc-shaped avoidance boss 11 is arranged inside the powder bin body. The boss is semicircular and provides the necessary installation and activity space for the developing roller. Two symmetrically arranged arc-shaped positioning members 12 are fixed on the arc surfaces on both sides of the developing roller arc-shaped avoidance boss 11, and the reserved space in the middle is just embedded in the developing roller positioning shaft ring 121. One end of the developing roller is connected to the conductive side cover 3 through the positioning shaft ring 121, which is convenient for quick disassembly and assembly;

[0027] At the other end of the powder bin body 1, i.e., the side close to the gear side cover 2, a developing roller positioning side plate 13 is integrally formed, and a driving notch 131 is opened on the side plate. The developing roller positioning structure 21 inside the gear side cover 2 is partially embedded in the driving notch 131 to ensure the accurate driving of the developing roller. The remaining space of the driving notch 131 is used to install a sealing collar 132. The other end of the developing roller passes through the sealing collar 132 and the gear side cover 2, and is connected to the developing roller driving gear 41 on the gear end cover 4. While ensuring power transmission, the sealing collar 132 plays a role in dust and leakage prevention.

[0028] In order to facilitate the addition of toner, a powder filling port 14 is provided at one end of the powder bin body 1 close to the conductive side cover 3, and is covered by the conductive side cover 3, so as to ensure the sealing and facilitate the user to manually fill the toner. In addition, in order to ensure the electrical safety and spatial positioning of the entire device, a conductive outer cover 5 is installed on the outer side of the conductive side cover 3, which not only defines the ideal distance between the powder bin body 1 and the waste toner bin of the toner box, but also provides necessary electrostatic protection;

These positioning columns are designed to precisely dock with the waste powder bin of the matching toner cartridge to ensure the accurate position between the two and improve the stability of the overall structure;

[0030] When performing maintenance on the developing roller, the operator only needs to gently pull the developing roller positioning collar 121, and the developing roller can be separated from one side of the conductive side cover 3 without removing any other parts, which greatly simplifies the maintenance process. Similarly, if the driving part needs to be maintained, the developing roller and the gear side cover 2 can be easily separated by loosening the sealing collar 132. The whole process is efficient and easy to operate.
