Abstract

The invention relates to a developer cartridge and a developer conveying device. A developer storage part and a developer supply part are arranged in the developer cartridge, toner is arranged in the developer cartridge, and a developer conveying device is arranged in the developer storage part. The developer conveying device comprises a support plate and a plurality of developer conveying plates, wherein the support plate can make reciprocating motion so as to approach or depart from the developer supply part; the developer conveying plates for conveying the toner are arranged on the support plate in a rotatable manner, the developer conveying plates comprise rotating shafts and blades, one ends of the blades are fixedly connected with the rotating shafts, and the other ends of the blades are free. The developer cartridge adopts the developer conveying plates which are connected to the support plate in a rotatable manner, and the developer conveying plates rotate in a certain range under the joint action of the motion of the support plate and the resistance of the toner so as to convey the toner. The conveying efficiency is high, the utilization rate of the toner is high, and the defects of the toner conveying structure in the prior art are better improved.

Description

technical field [0001] The present invention relates to a developer cartridge assembly, and more particularly, to a developer cartridge and a developer conveying device thereof. Background technique [0002] In the developer cartridge of the printer, it usually includes a developing roller, a toner feeding roller, toner, a toner chamber for accommodating the toner, and a stirring device. The stirring device is used to stir the toner in the powder bin to ensure smooth supply of toner. The stirring device generally includes a rotating shaft, a supporting arm disposed on the rotating shaft, and stirring blades disposed on the supporting arm. The stirring device is driven by the motor to make the blades rotate in the powder bin, which can sweep up the toner in the powder bin and transport it to the powder feeding roller. The defect of this stirring device is that the carbon powder cannot be supplied to the powder feeding roller evenly, and quality defects will occur during pri...
