Developing cartridge

A developing cartridge, detachably mounted in a device, wherein the developing cartridge comprises a housing, a chip, a developing member rotatably mounted in the housing, and a driving force receiving member located at a longitudinal end of the housing;

• the driving force receiving member is configured to receive a driving force from an outside of the developing cartridge to drive the developing member to rotate;
• and the chip is provided with an electrical contact;
• the developing cartridge further comprises a chip connection assembly, and at least a part of the chip connection assembly moves relative to the housing as a movable member between a first position and a second position;
• before the developing cartridge is mounted, the movable member is in the first position, and in this case, an electrical connection between the electrical contact and the device is broken, and then a communication connection is not established between the electrical contact and the device;
• and
• as the developing cartridge is mounted, the movable member moves from the first position to the second position, and in the second position, the movable member enables the electrical connection between the electrical contact and the device to be implemented, to establish the communication connection between the electrical contact and the device.
