process box

Abstract

The invention provides a processing box including a housing, a developing roller and a first sealing member. The housing surrounds a cavity for containing consumables. One end of the cavity is provided with a consumable outlet. The developing roller is installed in the cavity close to the consumable outlet. The second A seal is installed under the developing roller and fixed on the outlet of the consumables, wherein the process box further includes a sealing scraper, the sealing scraper includes a fixing part and a contact part, the fixing part is fixed on the outlet of the consumables, and the contact part includes a first end part and the contact end surface, the first end part abuts against the first sealing member, and the contact end surface elastically abuts against the developing roller. The process box uses the sealing scraper to elastically contact the developing roller, so that the sealing scraper is not easily deformed, which is beneficial to improving the sealing performance and durability of the process box.

Description

technical field [0001] The present invention relates to a process cartridge, and more particularly, to a process cartridge equipped with a sealing blade. Background technique [0002] Image imaging equipment is a device that uses the principle of electrophotographic imaging to form images on recording materials. Image imaging equipment includes copiers, printers, fax machines, and the like. Process cartridges used in image forming equipment are generally divided into two types, one is an integral process cartridge including a developing roller as a developing device and a photosensitive drum, and the other is a split process cartridge that separates the photosensitive drum to the outside. Both process cartridges are detachably mounted into the main body of the image forming apparatus. [0003] A typical image imaging device is a laser printer. Laser printers are one of the most widely used image imaging devices at present. Laser printers use the physical and chemical princi...

Problems solved by technology

[0006] Since the sealing blade 13 is in contact with the tangent surface of the developing roller 12, when the sealing blade 13 is slightly deformed, a gap will appear on the contact surface between the sealing blade 13 and the developing roller 12, resulting in a loose seal, resulting in toner 17 leak, pollute the environment

Simultaneously, because during the imaging process, the developing roller 12 will be shaken by the shaking of the printer body, causing the sealing blade 13 to not be in close contact with the developing roller 12, which will also cause the toner 17 to leak
