[0064] In some embodiments, the display support 711 is arranged as a colored insulating member, which can be arranged as a plastic member, facilitating processing and reducing production cost. It can be understood that in other embodiments, the display support 711 can be arranged as a colored glass member.

[0065] As shown in Figure 3 , the imaging assembly 3 and the powder cartridge assembly 6 in the embodiment adopt independent drive assemblies. The drive assembly 5 includes a first drive assembly 51 and a second drive assembly 52 which operate independently of each other. The first drive assembly 51 is connected to the imaging assembly 3, and the second drive assembly 52 is connected to the powder cartridge assembly 6. The first drive assembly 51 and the second drive assembly 52 are respectively driven to be connected to the power output head of the imaging device 2.

[0066] Specifically, the imaging assembly 3 includes a photosensitive drum 31 and a charging roller 32. The powder cartridge assembly 6 includes a developing roller 61, a powder feeding roller 62, a doctor blade 64, and a powder cartridge 63. The powder cartridge 63 stores toner. The powder feeding roller 62 transports the toner in the powder cartridge 63 to the outside of the powder cartridge 63. After receiving the toner, the developing roller 61 transports the toner to the photosensitive drum 31. After the developing roller 61 transports the toner, the doctor blade 64 scrapes and cleans the waste toner remaining on the developing roller 61, so that the developing roller 61 can stably transport the toner next time. Then, the photosensitive drum 31 receiving the toner converts the latent image into a toner image, so as to transfer the toner to a carrier medium such as paper.

[0068] Further, the second driving assembly 52 is provided with a second driving head 521 and a gear assembly 522, the second driving head 521 is used to drive the power output head connected to the imaging device 2, and the second driving head 521 is in transmission connection with the gear assembly 522, and the gear assembly 522 is in close connection with the developing roller 61 and the powder feeding roller 62, when the power output head of the imaging device 2 drives the second driving head 521 to rotate, the second driving head 521 drives the developing roller 61 and the powder feeding roller 62 to rotate through the gear assembly 522.

[0069] As shown in Figures 1-2 , 4, 6-9, the embodiment adopts a direct conductive mode to supply power to the imaging assembly 3 and the powder box assembly 6, one end of the conductive assembly 4 is inserted into the selenium drum to electrically connect the imaging assembly 3, and the other end of the conductive assembly 4 is exposed to the end of the selenium drum for abutting against the power supply part 21 on the imaging device 2 to supply power to the imaging assembly 3. Thus, the conductive assembly 4 is used to electrically connect the photosensitive drum 31, the charging roller 32, the developing roller 61, the powder feeding roller 62 and the doctor blade 64 to the corresponding power supply part 21 respectively. The conductive structure design directly contacts the selenium drum through the conductive assembly 4 to supply power, without the need for other conductive media, simplifying the structure and assembly process, improving the imaging stability, and reducing the cost.

[0070] In the embodiment, the photosensitive drum 31, the charging roller 32, the developing roller 61, the powder feeding roller 62 and the doctor blade 64 are respectively electrically connected to the corresponding power supply part 21 through the corresponding conductive sheet. However, due to the structural differences and different installation positions of the photosensitive drum 31, the charging roller 32, the developing roller 61, the powder feeding roller 62 and the doctor blade 64, the conductive sheets corresponding to the above structures will also be different in shape or position, but the conductive sheets corresponding to each structure are the same in structure and function, and can also stably achieve the electrical connection of the photosensitive drum 31, the charging roller 32, the developing roller 61, the powder feeding roller 62 and the doctor blade 64.

[0071] In the embodiment, the photosensitive drum 31, the charging roller 32, the developing roller 61, the powder feeding roller 62 and the doctor blade 64 are respectively electrically connected to the corresponding power supply part 21 through the corresponding conductive sheet. However, due to the structural differences and different installation positions of the photosensitive drum 31, the charging roller 32, the developing roller 61, the powder feeding roller 62 and the doctor blade 64, the conductive sheets corresponding to the above structures will also be different in shape or position, but the conductive sheets corresponding to each structure are the same in structure and function, and can also stably achieve the electrical connection of the photosensitive drum 31, the charging roller 32, the developing roller 61, the powder feeding roller 62 and the doctor blade 64. Figures 1-2 , 4, 6-9, the embodiment adopts a direct conductive mode to supply power to the imaging assembly 3 and the powder box assembly 6, one end of the conductive assembly 4 is inserted into the selenium drum to electrically connect the imaging assembly 3, and the other end of the conductive assembly 4 is exposed to the end of the selenium drum for abutting against the power supply part 21 on the imaging device 2 to supply power to the imaging assembly 3. Thus, the conductive assembly 4 is used to electrically connect the photosensitive drum 31, the charging roller 32, the developing roller 61, the powder feeding roller 62 and the doctor blade 64 to the corresponding power supply part 21 respectively. The conductive structure design directly contacts the selenium drum through the conductive assembly 4 to supply power, without the need for other conductive media, simplifying the structure and assembly process, improving the imaging stability, and reducing the cost.

The third conductive part 403 is provided with a charging shaft 311 along a third direction to connect to the end of the photosensitive drum 31. A charging shaft sleeve 312 is sleeved on the outside of the charging shaft 311. The charging shaft sleeve 312 is tightly connected to the end of the photosensitive drum 31. The directions of the first direction and the third direction are set to be different.

[0073] Furthermore, such as Figures 6-7 As shown, in some embodiments, taking the fourth conductive sheet 44 as an example, the fourth conductive sheet 44 includes a first conductive part 401, a second conductive part 402, and a third conductive part 403 connected in sequence. The first conductive part 401 extends along a first direction to connect to the power supply part 21. The third conductive part 403 is disposed along a third direction. One or more third conductive parts 403 can be provided. Here, two third conductive parts 403 are provided. The two third conductive parts 403 are respectively used to connect the powder feeding roller 62 and the scraper 64. The second conductive part 402 connects the first conductive part 401 and the third conductive part 403 along a second direction. Thus, the first conductive part 401 is the power receiving end, the third conductive part 403 is the power output end, and the second conductive part 402 is connected to transmit power from the first conductive part 401 to the third conductive part 403.

[0074] The second direction may be the same as or different from the first or third direction. The specific direction can be set according to the specific electrical structure of the toner cartridge; there are no restrictions here.

[0075] In this embodiment, the first conductive part 401, the second conductive part 402, and the third conductive part 403 are integrally formed. It is understood that in other embodiments, the first conductive part 401, the second conductive part 402, and the third conductive part 403 are welded together, or they are detachably connected. The emphasis here is on the electrical connection between the first conductive part 401, the second conductive part 402, and the third conductive part 403; therefore, the connection method is not limited to that described above.

[0076] In this embodiment, end caps 8 are provided at both ends of the drum. The end caps 8 are provided with conductive grooves 81 for accommodating conductive sheets. The conductive grooves 81 are lower than or flush with the bottom surface of the end caps 8. The conductive sheets are essentially embedded in the end caps 8 through the conductive grooves 81, which helps to protect the conductive sheets and reduce or avoid wear.
