The invention relates to a carbon powder box, which comprises a box body, a stirring device, a developing roller, a powder feeding roller, a layer thickness adjusting device, a powder removing opening and sealing element, wherein the box body is provided with a developing chamber and a powder chamber which are communicated with each other through a powder outlet; the stirring device is positioned in the powder chamber and is rotatably supported between two opposite side walls of the box body along the length direction; the developing roller is positioned in the developing chamber and is rotatablely supported between the two opposite side walls of the box body along the length direction; the powder feeding roller is positioned in the developing chamber, rotatablely supported between the two opposite side walls of the box body along the length direction close to the powder outlet, and in elastic contact with the developing roller; the layer thickness adjusting device is arranged on one wall of the box body and is used for adjusting the thickness of a carbon powder layer on the surface of the developing roller; the powder removing opening extends along the length direction of the box body and is formed on one box body wall of the developing chamber; and the sealing element is used for sealing the powder removing opening. The invention also relates to a method for removing powder from the developing chamber of the carbon powder box. The carbon powder box and the method have the characteristics of simple process, low cost and the like.
Description
Technical field [0001] The invention relates to a toner cartridge and a method for removing powder from a developing chamber of the toner cartridge. Background technique [0002] Printers and copiers are commonly used office equipment, and existing laser printers or copiers generally have replaceable toner cartridges. Under normal circumstances, the toner cartridge needs to undergo a full printing test after the assembly is completed, and it can be packaged and shipped after being qualified. There is a toner cartridge such as figure 1 As shown, it includes; a box body 1 provided with a developing chamber 11 and a powder chamber 12 that are communicated through a powder outlet 13; located in the powder chamber 12 and rotatably supported on two sides of the box body 1 along the length direction Stirring device (not shown) between opposite side walls; located in the developing chamber 11, the developing roller 15 and the powder feeding roller 16 are rotatably supported along the le...
