Toner cartridge

Abstract

The invention provides a toner cartridge. The toner cartridge comprises a body having a toner cavity for accommodating the toner, a developing roller which can be supported between two end walls of the box body in a manner of rotating around the axis of the developing roller and comprises a developing roller shaft supported on the two end walls of the box body, a toner feeding roller which can besupported between the two end walls of the box body in a manner of rotating around the axis of the toner feeding roller and comprises a toner feeding roller shaft supported on the two end walls of thebox body, a conductive plastic part, and a metal member, wherein the conductive plastic part has an electric contact point contact part and an output part, the electric contact point contact part isused for being in contact with an output electric contact point of imaging equipment, the output part is in contact with one end of the developing roller shaft / one end of the toner feeding roller shaft, two ends of the metal member are respectively in contact with the developing roller shaft and the toner feeding roller shaft, and the conductive plastic part and the metal member are arranged at an outer side of the same end wall of the body. The toner is stably transferred from the toner feeding roller to the developing roller, so the toner is more uniformly fed into the toner cartridge, andthe printing quality is stable. The toner cartridge has advantages of few parts, simple structure, few assembly procedures and lower cost.

Description

technical field [0001] The invention relates to the technical field of printing consumables, in particular to a toner cartridge detachably installed in an imaging device. Background technique [0002] Electrophotographic imaging equipment, such as laser printers, is a device that uses the principle of electrophotography to form an image on an image forming medium such as paper through processes such as charging, exposure, development, transfer, fixing, and cleaning. Imaging devices typically provide toner using a toner cartridge that is removably mounted therein. In addition to containing carbon powder, the toner cartridge is usually integrated with developing components such as a developing roller, a powder feeding roller, and a powder outlet knife. The thickness of the toner layer on the developing roller is adjusted, and the developing roller uses the toner carried on it to develop the electrostatic latent image on the photosensitive element. During the development proc...

AI Technical Summary

Problems solved by technology

Since the conductive parts are separated from each other and connected to the developing components respectively, the conductive end of the toner cartridge 1 has many components and has a complex structure, so that there are many procedures during assembly, and the cost of the toner cartridge 1 is relatively high.

Moreover, a plurality of conductive contacts that are separated from each other may cause the uneven voltage receiving the imaging device, causing the carbon powder on the toner cartridge 1 to be powdered unevenly when it is transferred from the powder chamber to the developing roller 12 and the photosensitive drum, thereby cause poor printing
