Developing box conductive separation structure and developing box applying same

Abstract

A developing box conductive separation structure comprises a framework, a conductive spring, a charging roller side sleeve, a buckle and an electric connecting sheet. The charging roller side sleevesare movably arranged at the two ends of the framework, and the charging rollers are borne on the charging roller side sleeves. The electric connecting piece is connected to the inner side of the framework and partially exposed out of the framework, the conductive spring is arranged in the framework, one end of the conductive spring is connected to the electric connecting piece, and the other end of the conductive spring penetrates through the charging roller side sleeve and abuts against the charging roller. The buckle is movably arranged on the charging roller in a sleeving manner. The framework is provided with a receding groove opened towards the buckle, the buckle is provided with an opening part with the caliber slightly larger than that of the charging roller, one side of the buckleis further provided with a stopping part, when the buckle is buckled in the receding groove in a rotating mode with the charging roller as the axis, the stopping part makes contact with the surface ofthe drum core, and the distance between a contact point and the charging roller is larger than the radius of the charging roller. The drum core and the charging roller can be separated and are in a stable state under the action of the conductive spring, so that poor printing quality caused by deformation of the drum core and the charging roller due to contact is avoided.

Description

technical field [0001] The present invention relates to the field of developer cartridges, in particular to a conductive separation structure of the developer cartridge, which separates the charging roller from the drum core in an idle state such as storage and transportation, so as to avoid deformation of the charging roller and the drum core due to extrusion; it also relates to a device and its application A developing cartridge with a conductive separation structure. Background technique [0002] An electronic imaging device is a device that forms an image on a recording material through electrophotographic imaging processing technology, such as: electrophotographic copying, laser printers, electrophotographic printers, fax machines, word processors, etc., where the electronic imaging device mainly includes The main frame and the developing box are equipped with parts required to form an image. There is a space for installing the developing box inside the main frame, and ...

AI Technical Summary

Problems solved by technology

[0004] In practice, when the developing cartridge is stored and transported for a long period of time, if the rigid part is always in contact with the developing element, the rubber layer covering the surface of the developing element will be squeezed and deformed by the rigid part, which will affect the development of the developing cartridge.
