Developing cartridge, process cartridge and image forming apparatus

Abstract

The present application relates to the field of image forming technology, and in particular to a developer cartridge, a process cartridge and image forming equipment. The process cartridge includes: electrical connection; drum box, the drum box includes a drum box chip; a conductive connector, when the developer cartridge and the drum box are installed, the conductive connector moves toward the bottom surface of the drum box and is electrically connected to the drum box chip. The process cartridge connects the developing cartridge chip and the drum cartridge chip through conductive connectors, so the identification information of the developing cartridge and the drum cartridge and the content of the internal developer or waste developer can be detected only through the developing cartridge chip without simultaneously passing through the developing cartridge chip. Cartridge chips and drum cartridge chips achieve this purpose, so the process cartridge can reduce the number of contacts that cooperate with the developer cartridge chip and the drum cartridge chip, thereby reducing the design difficulty of the process cartridge, while preventing the developer cartridge chip and the drum cartridge chip from interacting with each other. There is a problem of poor conduction between the contacts.

Description

technical field [0001] The present application relates to the technical field of image formation, in particular to a developing box, a process box and image forming equipment. Background technique [0002] Image forming equipment such as printers, copiers, etc. all need to be provided with a process cartridge. In the prior art, there is a split process cartridge, which includes a developing cartridge and a drum cartridge. The developing cartridge and the drum cartridge can be relatively disassembled. There is a developer cartridge chip, and a drum cartridge chip is installed in the drum cartridge, which are used to store information such as toner content and number of printed pages. Correspondingly, contacts are provided on the side wall or other positions of the image forming device, and the contacts can be in contact with the chip of the developing cartridge and the chip of the drum cartridge respectively, so as to detect the identification information of the developing ca...

AI Technical Summary

Problems solved by technology

Corresponding to the developer cartridge chip and the drum cartridge chip, two sets of contacts need to be designed to contact the developer cartridge chip and the drum cartridge chip respectively. Poor conduction between points is prone to problems

In addition, this kind of side-sliding contact makes the developing cartridge chip and the drum cartridge chip easily scratched, which also leads to the problem of poor conduction
