Embodiment 1

[0029] Such as image 3 Shown is the first developer cartridge, image 3 It is a schematic diagram of removing the gear cover from the developer cartridge 1. This embodiment provides a developer cartridge 1 detachably installed on an electrophotographic imaging device. The developer cartridge 1 includes a box body 10, a detection gear 2, a gear transmission mechanism 3 and a gear Cover 4 ( figure 1 shown). Such as Figure 4a to Figure 6a As shown, the developing cartridge also includes a bracket 6, a developing element 53, a powder feeding element 52 and a stirring element 51; the box body 10 includes a side wall 101, and the side wall 101 includes a first protrusion 101a with a through hole, a second protrusion 101a with a through hole. The protrusion 101b and the opening 101c; the stirring element 51 passes through the first protrusion 101a with a through hole, and the powder feeding element 52 passes through the second protrusion 101b with a through hole; the developer i...

Embodiment 2

[0037] Unless otherwise specified, the developing cartridge used in this embodiment is the same as that in Embodiment 1.

[0038] The bracket in this embodiment can only locate the detection gear, that is, the bracket only includes a main body, a third positioning post, a positioning protrusion and a buckle or a through hole, and the third positioning post and the buckle or through hole are arranged on the main body; The second main body, the first hollow cylinder, the second hollow cylinder, the third hollow cylinder, the first positioning column, the second positioning column, the first buckle and the second buckle are composed of the second bracket, the first hollow cylinder, the second hollow The cylinder, the third hollow cylinder, the first positioning column, the second positioning column, the first buckle and the second buckle are arranged on the second main body; the bracket and the box are connected by buckles or positioned by screws and through holes , the box body ...

Abstract

The invention relates to a developing box. The developing box comprises a box body for containing a developing agent and an external element; the external element characterizes the characteristic information of the developing box; the developing box also comprises a middle element, which is detachably arranged on the side wall of the box body, the external element is installed on the side wall of the box body through the middle element, thus the middle element can also characterize the characteristic information of the developing box, so that the box body does not characterize the characteristic information of the developing box so as to increase the universality of the box body, and the technical problem that the universality of the box bodies of the conventional developing boxes is low is solved.

Description

technical field [0001] The invention relates to a developing cartridge. Background technique [0002] Electrophotographic imaging devices, such as laser printers, copiers, and facsimile machines, use a processing unit detachably mounted thereon; the processing unit includes a photosensitive drum unit and a developing cartridge; the photosensitive drum unit includes a photosensitive drum, Charging unit and drum frame. Such as figure 1 , Figure 2a and Figure 2b As shown, the developing cartridge A includes a detection gear 2, a gear transmission mechanism 3, a gear cover 4, a box body 100 and a positioning post 100a for positioning the detection gear; the detecting gear 2 is detected by an electrophotographic imaging device, so that the developing cartridge A The model and new and old information of the electrophotographic imaging device are transmitted to the electrophotographic imaging device; the box body 100 contains developer, and the detection gear 2 is installed o...
