Embodiment 1

[0047] Figure 6A It can be used as a schematic structural diagram of the removable part 35 of this embodiment. As shown in the figure, along the first vertical side 35b1, the length W41 of the first vertical side 35b1 is connected to the first sealing edge 35a and the third sealing edge 35c. The length W4 of the second sealing edge 35b between them 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 above two is also W41≥W4*1 / 4 is satisfied, therefore, the first vertical side 35b1 does not affect the flow of the developer along the longitudinal direction of the developer supply port 130; the variable portion includes an inclined side 35b2, and 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 ot...

Embodiment 2

[0069] Figure 6J is a partial schematic view of the sealing portion of the sealing member in this embodiment. The seal structure involved in this embodiment is substantially the same as the seal structure in the above embodiments, therefore, the same components will use the same names and symbols. As shown in the figure, the difference between the sealing member in this embodiment and the sealing member in the above-mentioned embodiments is that the second sealing edge 35b of the sealing portion 352 in the sealing member 34 of this embodiment is not all located on the first sealing edge. Between the edge 35a and the third sealing edge 35c.

[0070] Such as Figure 6J As shown, the second sealing edge 35b includes a first vertical edge 35b1 and a variable portion 35b0 connected to each other, and the length W41 of the first vertical edge 35b1 is the same as The length W4 of the second sealing edge 35b between the sides 35c satisfies W41>W4; the first vertical edge 35b1 is c...

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 seal and a developing cartridge with the seal. Background technique [0002] A developing cartridge is an essential part of an electrophotographic imaging device, whether it is a so-called one-piece developing cartridge containing a photosensitive member therein, or a so-called split developing cartridge in which a photosensitive member is placed in an electrophotographic imaging device without a photosensitive member, Before the end user uses it, it is necessary for the manufacturer to 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 for use by the end user. [0003] figure 1 It is a schematic diagram of the structure of the developer cartridge A. The devel...
