Embodiment 1

[0047] Figure 6A It can be used as a schematic structural diagram of the removable member 35 of this embodiment. As shown in the figure, along the first vertical side 35b1, the length W41 of the first vertical side 35b1 and the first sealing side 35a and the third sealing side 35c The length W4 of the second sealing edge 35b in between satisfies W41<W4, that is, the second sealing edge 35b is all located between the first sealing edge 35a and the third sealing edge 35c. Preferably, the length relationship between the two is still W41≥W4*1 / 4 is satisfied, therefore, the first vertical side 35b1 along the longitudinal direction of the developer supply port 130 will not affect the flow of the developer; the variable part includes an inclined side 35b2, the first vertical side 35b1 is respectively connected to one of the first sealing edge 35a and the third sealing edge 35c and the inclined edge 35b2, and the inclined edge 35b2 is also connected to the other of the first sealing ed...

Embodiment 2

[0069] Figure 6J It is a partial schematic diagram of the sealing part of the seal in this embodiment. The structure of the seal involved in this embodiment is substantially the same as the structure of the seal in the foregoing embodiment. Therefore, the same components will have the same names and reference numbers. As shown in the figure, the difference between the seal in this embodiment and the seal in the above embodiment is that the second sealing edge 35b of the sealing portion 352 in the seal 34 in this embodiment is not all located in the first seal. Between the side 35a and the third sealing side 35c.

[0070] Such as Figure 6J As shown, the second sealing edge 35b includes a first vertical edge 35b1 and a variable portion 35b0 that are connected to each other. The length W41 of the first vertical edge 35b1 is the same as the first sealing edge 35a and the third sealing edge 35b1 located along the first vertical edge 35b1. The length W4 of the second sealing edge 35...

Abstract

The invention relates to a sealing element and a developing box with the same. The sealing element comprises a removable element with a sealing part, and a first sealing edge, a second sealing edge, a third sealing edge and a fourth sealing edge are formed in the periphery of the sealing part; the second sealing edge comprises a first perpendicular edge and a variable part which are connected, the first perpendicular edge is connected with one of the first sealing edge and the third sealing edge, and the variable part is connected with the other one of the first sealing edge and the third sealing edge; as the first perpendicular edge exists, a part of developer supplying openings cannot be shielded all the time in the horizontal direction of the developer supplying openings, and the ends of the developer supplying openings can supply a proper amount of developers all the time.

Description

Technical field [0001] The invention relates to the field of electrophotographic imaging, in particular to a sealing element and a developing cartridge with the sealing element. Background technique [0002] The developing cartridge is an indispensable component in the electrophotographic imaging equipment, whether it is a so-called integrated developing cartridge containing a photosensitive member or a so-called split developing cartridge in which the photosensitive member is placed in the electrophotographic imaging device without the photosensitive member, Before the end user uses it, the manufacturer must ensure that the developer cartridge is well sealed. One of the most important parts is the developer supply port of the developer cartridge. Generally, the manufacturer uses a special seal to seal the developer The supply port is sealed, and the seal is opened when the end user uses it. [0003] figure 1 It is a schematic diagram of the structure of the developing cartridge A...
