Title:
DEVELOPING CARTRIDGE
Document Type and Number:
WIPO Patent Application WO/2024/099371
Kind Code:
A1
Abstract:
A developing cartridge, detachably mounted in an imaging device, the imaging device being provided with a separating force output member (700). The developing cartridge comprises a developing frame, a receiving and separating assembly, a protection assembly, and a developing roller (200). The developing frame comprises a toner hopper (100); the developing roller (200) is rotatably arranged on the developing frame; the receiving and separating assembly comprises a force bearing member (510); the force bearing member (510) is used for receiving an acting force output by the separating force output member (700); the protection assembly is disposed at the end portion of the toner hopper (100) in the length direction; and observed in the axis direction of the developing roller (200), the force bearing member (510) does not protrude from the protection assembly. Since the force bearing member (510) does not protrude from the protection assembly, that is, all parts of the force bearing member (510) are completely covered by the protection assembly, the protection assembly can block impact and collision from the outside and protect the force bearing member (510), thereby preventing the force bearing member (510) from being damaged during transportation, and further avoiding the influence on the use of the developing cartridge.
