As shown in fig. 2 and 3, the process cartridge of the present embodiment includes a casing 1, and a photosensitive drum, a developing roller, a powder feed roller, a powder hopper containing developer, and the like are provided in the casing 1. A developing roller conductive bracket 2 and a powder feeding roller conductive bracket 3 are arranged at one end of the shell 1. The developing roller conductive bracket 2 is connected with one end 4 of the developing roller exposed out of the shell 1, and the powder feeding roller conductive bracket 3 is connected with one end 5 of the powder feeding roller exposed out of the shell 1. The developing roller conductive bracket 2 and the powder feeding roller conductive bracket 3 are contacted with each other. The present embodiment provides a conductive contact portion 3a for contacting a conductive contact of the image forming apparatus on the powder feeding roller conductive holder 3, and one end of the developing roller conductive holder 2 is fitted to the powder feeding roller conductive holder 3.

When the processing box is installed after falling off, and printing is carried out, the conductive contact of the image forming equipment is contacted with the conductive contact part 3a on the conductive bracket of the powder feeding roller, and the powder feeding roller is electrified; and because the powder feeding roller conductive support 3 is also contacted with the developing roller conductive support 2 at the same time, although no conductive contact part is arranged on the developing roller conductive support 2, the conductive contact of the image forming device can not be directly contacted with the developing roller conductive support 2, but the developing roller conductive support 2 can also electrify the developing roller through the contact with the powder feeding roller conductive support 3. Moreover, the conductive bracket of the developing roller can have a corresponding resistance value by adjusting the material of the conductive bracket of the developing roller, so that the voltage transmitted by the conductive bracket of the powder feeding roller is reduced, and the desired printing effect is achieved.

Fig. 4 is a schematic structural diagram of another embodiment of the present invention, in the former embodiment, the developing roller conductive bracket 2 is located inside the powder feeding roller conductive bracket 3, and the end portion thereof is provided with an assembling hole to be assembled with the powder feeding roller conductive bracket 3, and the developing roller conductive bracket 2 and the powder feeding roller conductive bracket 3 can be assembled together through a fastening member such as a screw or a pin shaft arranged on the end wall of the housing. The developing roller conductive bracket 2 in this embodiment is located outside the powder feeding roller conductive bracket 3, i.e., the powder feeding roller conductive bracket 3 is adjacent to the end wall of the process cartridge case. The developing roller conductive support 2 and the powder feeding roller conductive support 3 are provided with corresponding assembling holes (grooves), the developing roller conductive support 2 and the powder feeding roller conductive support 3 are assembled together through the assembling holes (grooves), so that the developing roller conductive support 2 and the powder feeding roller conductive support 3 are contacted with each other, when the conductive contact part 3a of the powder feeding roller conductive support 3 is contacted with the conductive contact of the image forming device, the powder feeding roller conductive support 3 enables the powder feeding roller to be electrified, and the developing roller is electrified through the developing roller conductive support 2 contacted with the powder feeding roller conductive support.

Example 2

In embodiment 1, the conductive contact portion that contacts the image forming apparatus is provided on the powder feeding roller conductive holder 3, but the conductive contact portion may be provided on the developing roller conductive holder 2.

When the conductive contact part 2a contacts with the conductive contact on the image forming apparatus, the developing roller and the powder feeding roller can be electrified simultaneously by the developing roller conductive bracket 2 and the powder feeding roller conductive bracket 3 which are connected into a whole. As long as one of the developing roller conductive support and the powder feeding roller conductive support is provided with a conductive contact part which is contacted with a conductive contact of the image forming device, the developing roller conductive support and the powder feeding roller conductive support can be electrically connected through mutual contact, so that the structure of the processing box is simplified.
