Embodiment 1

[0036] like figure 1 , figure 2 As shown, the toner cartridge is mainly composed of a developing unit 1 and a photoreceptor unit 2 . The developing unit 1 includes a developing roller 4 , and the two sides of the developing unit 1 are respectively provided with front guide posts 6A, 6B and rear guide posts 7A, 7B.

[0037] like image 3 , Figure 4 As shown, the photoreceptor unit 2 includes a photoreceptor drum 5, and front guide rails 8A, 8B, rear guide rails 9A, 9B, side flap holes 12A, 12B and top strap holes 13A, 13B are respectively provided on both sides of the photoreceptor unit 2.

[0038] like Figure 5 , Image 6 As shown, side buckles 10A, 10B, top buckles 11A, 11B and compression springs 14A, 14B are provided on the elastic brackets 3A, 3B.

[0039] like Figure 7 , Figure 8 As shown, since the distance between the two sides of the photoreceptor unit 2 is slightly larger than the size between the two sides of the developing unit 1, the developing unit 1 ...

Embodiment 2

[0043] like Figure 11 , 12 , 13, 14 are another embodiment of the present invention;

[0044] Compared with Embodiment 1, the developing unit 1 adopted in this embodiment has only the front guide posts 6A and 6B, and the photoreceptor unit 2 has only the front guide rails 8A and 8B. The process box structure that the present embodiment adopts does not have embodiment one described rear guide post 7A, 7B and rear guide rail 9A and 9B, on the elastic support 3A' more than embodiment one described elastic support 3A a supporting plate 15A. The support plate 15A is used to support the rear of the developing unit and prevent it from falling.

[0045]The compression springs 14A and 14B used in the present invention can also be a group of magnets, one of which is arranged on the developing unit 1, and the other is arranged on the photoreceptor unit 2, and the magnetic force of the group of magnets makes the developing unit 1 The developing roller 4 moves toward the direction clos...

Abstract

The invention relates to a powdered carbon box in an electrophotographic imaging device, comprising a developing unit and a photoreceptor unit which are installed together in a detachable way. The developing unit at least comprises a developing roller, and the photoreceptor unit at least comprises a photosensive drum; and the developing roller and the photosensitive drum are matched so as to leadthe developing roller to be capable of providing powdered carbon to an electro-static latent image on the photosensitive drum effectively, thus froming a developing image. The powdered carbon box further comprises an elastic part and an elastic bracket which is connected with the developing unit or the photosensitive unit in a detachable way, wherein the free end of the elastic part is connected with and forcibly pushes the photosensitive unit or the developing unit so as to lead the developing roller to close up the photosensitive drum.

Description

technical field [0001] The invention relates to a toner cartridge in an electrophotographic imaging device. Background technique [0002] Electrophotographic imaging devices, especially toner cartridges for laser printers, are mainly composed of a developing unit and a photoreceptor unit connected in a certain way. The developing unit is mainly composed of a toner chamber, agitator, developing roller and feeding The photoreceptor unit is mainly composed of a photosensitive drum, a charging roller and a waste toner bin. The photosensitive drum is exposed to laser light to form an electrostatic latent image thereon, and the developing roller supplies toner to the photosensitive drum to form an image corresponding to the electrostatic latent image. The toner cartridge uses a certain connection method to tightly connect the developing unit and the photosensitive body unit, so that the developing roller in the developing unit and the photosensitive drum in the photosensitive bod...
