Description

TECHNICAL FIELD

[0001] The utility model relates to image forming technology, especially a kind of process cartridge. BACKGROUND

[0002] The developing roller or photosensitive drum of process cartridge is made of elastomer material, and indentation is easily formed during long-time storage, and the risk of collision and scratch is easily caused during transportation. In order to protect it, a protective sheet is usually used to wrap it. When the process cartridge is used, the protective sheet needs to be pulled out before use. However, during the testing process before the process cartridge is shipped, residual powder (developer) is left, which causes the protective sheet to be contaminated with residual powder. Or during transportation, the protective sheet comes into contact with the developing roller or photosensitive drum, thereby contaminating the developer. Therefore, when the protective sheet is pulled out, some residual powder will be taken out, thereby affecting the use environment and reducing the user experience.

[0003] In addition, in order to prevent developer leakage, some process cartridges use a seal to seal the powder bin. Before use, the seal needs to be pulled out. Since the seal is contaminated with developer, pulling out the seal will take out residual powder, which will affect the use environment and reduce the user experience. SUMMARY
