Embodiment 1

[0036] Such as figure 1 , 2 As shown in 3, the developing box 11 includes a box body 12, a photosensitive element 13 and a developing element 14; the developing element 14 is fixedly supported on the box body 12 and is not movable relative to the box body 12; the box body 12 is provided with a rotating wheel 15. The rotating wheel 15 is provided with a driving rod 15a2; the photosensitive element 13 is supported by the rotating wheel 15 through the photosensitive element support shaft, and the rotation center 15a of the rotating wheel 15 and the photosensitive element rotation center 13a are not on the same line (relatively eccentrically arranged). The photosensitive element 13 moves back and forth relative to the box body 12 to approach or move away from the developing element when the rotating wheel 15 rotates in the forward and reverse directions around its center of rotation. The image forming apparatus is provided with a guide rail 110, a first stop post 120a, and a second ...

Embodiment 2

[0042] Such as Figure 4 , 5 , 6 shows the second embodiment of the present invention; in this embodiment, the structure of the developer cartridge 21 is the same as the structure of the developer cartridge in the first embodiment, and will not be repeated here; 22 shown in the figure is the developer cartridge box 23a, 24a, 25a are the rotation center of the photosensitive element, the rotation center of the developing element and the rotation center of the rotating wheel respectively; the image forming device is provided with a guide rail 210, a first rotating member 220a, a second rotating member 220b, and a stop 220c; The rotating wheel 25 on the box 21 can slide along the guide rail 210, and the first rotating member 220a and the second rotating member 220b can respectively rotate around their respective centers of rotation;

[0043] During the process of mounting the developing cartridge to the image forming apparatus, when the second rotating member 220b is in contact with ...

Embodiment 3

[0047] Such as Figure 7 , 8 Shown is the third embodiment of the present invention; the developing cartridge 31 includes a box body 32, a photosensitive element 33, a rotating wheel 34, a stud 35 and a developing element (not shown); the rotating wheel 34 is arranged at the end of the photosensitive element 33 , Used to support the photosensitive element 33 on the two ends of the box body 32; the protrusion 35 is arranged on the box body 32 and is formed integrally with the box body 32; the image forming device includes an upper rail 311 and a rail 312; the rail 312 includes a A curved portion 312a that is bent downward.

[0048] When the developing cartridge is installed on the image forming device, such as Figure 7 As shown, the rotating wheel 34 and the protrusion 35 on the box body 32 slide along the upper guide rail 311 and the guide rail 312. At this time, the photosensitive element 33 and the developing element in the developing box 31 are in a non-contact state.

Abstract

The invention relates to a developing box, an image formation apparatus which matches with and is used together with the developing box, and image formation equipment containing the developing box and the image formation apparatus. A rotor wheel on the developing box can rotate in both negative and positive directions around the rotation center. A driving mechanism which fits with a driving rod is disposed in an accommodation space on the image formation apparatus. When the developing box is installed into the accommodation space, the driving mechanism drives the driving rod to drive the rotor wheel so as to make a photosensitive element compress a developing element tightly. When the developing box is dismounted from the accommodation space, the driving mechanism drives the driving rod to drive the rotor wheel so as to make the photosensitive element return to an original state far from the developing element. Therefore, the photosensitive element is separated from the developing element when the developing box is dismounted from the accommodation space, and the technical problem of present developing boxes that the photosensitive element and the developing element still contact with each other after the developing box is removed from the image formation apparatus such that pollution is generated between the photosensitive element and the developing element is solved.

Description

Technical field [0001] The present invention relates to a developing cartridge, an image forming device matched with it, and an image forming apparatus including the developing cartridge and the image forming device. Background technique [0002] United States Published Patent US20070053717 discloses a developing cartridge, which includes a cartridge body, a photosensitive element, a developing element and side plates arranged at both ends of the cartridge body; the developing element is relatively fixedly supported on the cartridge body; The side plates are fixedly arranged at both ends of the box body; the photosensitive element is supported by a photosensitive element support shaft, and both ends of the photosensitive element support shaft are provided with rotating wheels, and the rotating wheels are rotatably supported on the side plates. The photosensitive element is movable relative to the side plates at both ends, the rotation center of the rotating wheel on the side plat...
