AI Technical Summary
Technical Problem
Existing process cartridges for electronic image-forming apparatuses have a complex dual-drive structure, leading to high costs and complexity.
Method used
A process cartridge with a simple single-drive structure, where a driving head is used to transmit rotational force to both the photosensitive drum and the developing roller through a single force-receiving part, reducing the need for complex coupling mechanisms.
Benefits of technology
The single-drive structure simplifies the electronic image-forming apparatus and process cartridge design, reducing costs and improving operational efficiency while maintaining effective image formation.

Abstract
The present disclosure provides a process cartridge. The process cartridge comprising a cartridge body, a photosensitive drum, a developing roller and a driving assembly, the photosensitive drum and the developing roller are rotatably disposed on the cartridge body, wherein the developing roller includes a first position and a second position relative to the photosensitive drum, and when the developing roller is in the second position, the developing roller is separated from the photosensitive drum; the driving assembly, disposed at an end of the cartridge body, wherein the driving assembly includes a first force-receiving part; the first force-receiving part is configured to receive a driving force outputted by a driving head of an electronic image-forming apparatus to rotate when receiving the driving force; and the photosensitive drum and the developing roller are both capable of receiving the driving force transmitted by the first force-receiving part to rotate when receiving the driving force. The present disclosure adopts a single driving mode, the structure of the process cartridge is relatively simple with reduced cost, and when the developing roller is in the second position, the third transmission part may be always meshed with the first transmission part and the second transmission part, thereby the developing roller and the photosensitive drum may change from the separation state to the contact state more smoothly.
