Abstract

The invention discloses a highly sealed toner cartridge, which comprises a developing frame, a photosensitive drum, an auxiliary waste toner collecting box and a toner frame, the toner frame is installed on the developing frame, a toner container is installed in the toner frame, and A developing sleeve is installed, both ends of the developing sleeve can be rotatably set on the developing frame, both ends of the photosensitive drum can be rotatably set on the waste toner frame, and a waste toner container is installed in the waste toner frame . The high-seal toner cartridge is equipped with a cleaning sponge and an auxiliary waste toner collection box on the waste toner frame of the toner cartridge to prevent leakage of toner, because the distance from the auxiliary waste toner collection box to the central axis of the photosensitive drum is smaller than that from the cleaning scraper to the photosensitive drum. The distance from the central axis of the drum, so the toner falling out of the waste toner container is collected by the auxiliary waste toner collection box. In this way, toner leakage is well avoided. promote.

Description

technical field [0001] The invention relates to the technical field of laser printer spare parts, in particular to a highly sealed toner cartridge. Background technique [0002] Because of its fast and high-definition printing quality, laser printers occupy an increasingly important position in daily office printing devices. In laser printers, the toner cartridge, one of the core components, carries the key to the electrostatic latent image in the laser printing process. Task. The laser converts the text or graphic information sent by the computer into a laser beam, scans through the axis of the photosensitive drum at a constant speed, and then forms an electrostatic latent image corresponding to the text or graphic information sent to be printed, and then develops, converts Printing and fusing to get high-quality prints. [0003] Although the existing toner cartridges have experienced the development from the original integral type to the later separated type, the separat...
