AI Technical Summary
The existing grounding element structure of the developing cartridge is complex and has many components, which affects the overall size of the developing cartridge. In addition, the assembly process is complicated and there is a risk of electric field interference and short circuit.
An integrated grounding element is adopted, which connects the metal sleeve and the metal substrate through the grounding element. The grounding element has a V-shaped structure and has a first positioning part and a second positioning part, which enhances stability and simplifies the structure.
The structure of the grounding element is simplified, the space occupied is reduced, the size of the developing cartridge is not affected, assembly steps are saved, and the stability and reliability of the electrical connection are improved.
