<p>A carbon powder cartridge (100) for the laser printer comprises a developing roller (104), a powder supply roller (103), a layer-thickness regulator, a powder supply rack (107), and a carbon powder bin (101), wherein the developing roller (104) and the powder supply roller (107) are axially arranged on the cartridge body (105) of the carbon powder cartridge (100) in parallel. The carbon powder bin (101) is a hollow cavity for containing the carbon powder in the cartridge body (105). The powder supply rack (107) comprises a support shaft (108) and a powder supply plate (110) fixedly connected with the support shaft (108) through a spoke (109). The powder supply rack (107) is supported in the carbon powder bin (101) in the mode that the support shaft (108) is parallel to the middle shaft of the developing roller (104). The powder supply plate (110) extends in the direction parallel to the support shaft (108). The appearance of the powder supply plate (110) is in a triangular shape on the axial cross section of the support shaft (108). One edge of the triangle is the outer edge part of the radius extension line of the support shaft (108), and the top angle which the one edge faces points to the rotary advancing direction of the support shaft (108).</p> |
