[ background of the invention ]

Process cartridges are widely used as replaceable consumables in electronic image forming apparatuses such as printers, copiers, and the like. The electronic imaging device mainly works in the following processes in the imaging process: the charging assembly charges the photosensitive member surface with a uniform predetermined charge; forming an electrostatic latent image on the surface of the photosensitive member having a predetermined charge after exposure treatment; the developing component sends the developer to the photosensitive component to develop the electrostatic latent image on the surface of the photosensitive component; after the transfer, the developer on the electrostatic latent image is transferred to an image recording medium such as a paper sheet; the cleaning assembly cleans the incompletely transferred developer on the photosensitive member surface to let the photosensitive member enter the next charging, i.e., the next cycle process.

During this cycle, the process cartridge portion includes at least a charging member for charging the photosensitive member, and a developing member for supplying the photosensitive member with the developer. In the prior art, the photosensitive element is a photosensitive drum, and the developing element is a developing roller. The process cartridge itself does not contain a driving force generating part such as a motor, but receives a rotational driving force from the electronic image forming apparatus on which it is located. Because the processing box is a replaceable consumable used on the electronic imaging device, the processing box can be replaced independently for ensuring that a common user can easily, and the power receiving part arranged on the processing box and the power transmission part arranged on the electronic imaging device can be coupled when the rotary driving force is received and separated when the rotary driving force is not transmitted.
