Along the X direction, themovable portion 52 is One end of the sealingportion 51 is folded, and along the Z direction, at least a part of themovable portion 52 overlaps with the sealingportion 51 , and thehandle portion 53 is exposed through theopening 251 provided in thegroove portion 25 . Before theprocess box 100 is used, along the X direction, thehandle part 53 is pulled away from theprocess box 100 and themovable part 52 is driven to drive the sealingpart 51 away from theinner wall 261 until the sealingpart 5 is completely removed to theprocess box 100 external. In this embodiment, the sealingmember 5 is welded or bonded to theinner wall 261 facing thedeveloper chamber 201. When the developer added in theprocess cartridge 100 is not fully used, the remaining developer will fall on the sealingmember 5 facing the developing agent.Roller 21 surface, when theseal 5 is removed away from theprocess cartridge 100, the remaining developer will drop directly into thedeveloper chamber 201 as theseal 5 is separated from theinner side wall 261, so the remaining developer Agents can also be utilized, which reduces waste and saves resources. At the same time, the remaining developer will not be taken out by the sealingmember 5, which can also reduce the pollution to the operating environment and the natural environment, and can also enable users to obtain better user experience.

参见图6、图7A、图7B，密封件5可按照如下步骤进行安装：Referring to Figure 6, Figure 7A, and Figure 7B, theseal 5 can be installed according to the following steps:

安装密封部51的步骤，将密封部51与内侧壁261结合，以密封连通口27；The step of installing the sealingpart 51 is to combine the sealingpart 51 with theinner side wall 261 to seal thecommunication port 27;

折叠活动部52的步骤，将活动部52从密封部51的一个末端折叠；the step of folding themovable part 52, folding themovable part 52 from one end of the sealingpart 51;

暴露手持部53的步骤，将手持部53穿过开口251，使手持部53向外暴露。In the step of exposing thehandle portion 53 , thehandle portion 53 is passed through theopening 251 to expose thehandle portion 53 to the outside.

在安装密封部51的步骤中，通过将密封部51焊接或粘接于内侧壁261以实现密封部51 的安装；在折叠活动部52的步骤中，从密封部51的一个末端折叠活动部52；在暴露手持部 53的步骤中，将手持部53从显影剂腔201穿过开口251，使手持部53暴露。In the step of installing the sealingportion 51, the sealingportion 51 is installed by welding or bonding the sealingportion 51 to theinner sidewall 261; in the step of folding themovable portion 52, themovable portion 52 is folded from one end of the sealingportion 51 ; In the step of exposing thehandle portion 53, thehandle portion 53 is passed through the opening 251 from thedeveloper chamber 201, so that thehandle portion 53 is exposed.

进一步的，如图8所示，在Z方向上，开口251位于内侧壁261的-Z方向，在本实施例中，开口251的第一端2511与内侧壁261在Z方向的间隔距离h大于1mm。由于密封件5面向存储显影剂的显影剂腔201，若显影剂腔201中的显影剂带有静电则会被吸附至活动部52 或密封部51，当拉动手持部53时，一方面，开口251与内侧壁261之间的间隔可以使被吸附而聚集的显影剂重新掉回显影剂腔201，另一方面，处理盒100进行测试需要在显影辊21 所在侧添加一定量的显影剂，与密封件5设置在面向显影辊21的外侧壁262相比，密封件5 设置在面向显影剂腔201的内侧壁261时，因静电而被吸附的显影剂量少，因此本实施例可以减少被密封件5带出的显影剂量或避免显影剂被密封件5带出，而且还可以避免显影剂被密封件5包裹而导致密封件5无法被拉出。另外，当显影剂腔201装满显影剂而顶住密封件 5时，由于开口251与内侧壁261之间存在间隔，当拉动手持部53时，靠近开口251的密封件5会沿箭头I所示向显影剂腔201内部挤压显影剂(如图7B所示)，因此密封件5不会被完全顶住，从而避免无法拉动密封件5的情况。Further, as shown in FIG. 8, in the Z direction, theopening 251 is located in the -Z direction of theinner wall 261. In this embodiment, the distance h between thefirst end 2511 of theopening 251 and theinner wall 261 in the Z direction is greater than 1mm. Since the sealingmember 5 faces thedeveloper chamber 201 that stores the developer, if the developer in thedeveloper chamber 201 has static electricity, it will be attracted to themovable part 52 or the sealingpart 51. When thehandle part 53 is pulled, on the one hand, the opening The space between 251 and theinner side wall 261 can make the developer that is absorbed and accumulated fall back into thedeveloper chamber 201. On the other hand, theprocess cartridge 100 needs to add a certain amount of developer on the side where the developingroller 21 is located for testing. Compared with the sealingmember 5 arranged on theouter wall 262 facing the developingroller 21, when the sealingmember 5 is arranged on theinner wall 261 facing thedeveloper chamber 201, the amount of developer adsorbed by static electricity is small, so this embodiment can reduce the amount of developer being sealed. The amount of developer carried out by themember 5 may prevent the developer from being carried out by the sealingmember 5, and it may also prevent the developer from being wrapped by the sealingmember 5 so that the sealingmember 5 cannot be pulled out. In addition, when thedeveloper chamber 201 is filled with developer and presses against the sealingmember 5, due to the gap between theopening 251 and theinner wall 261, when thehandle 53 is pulled, the sealingmember 5 close to theopening 251 will move along the direction indicated by the arrow I. The developer is squeezed into the developer chamber 201 (as shown in FIG. 7B ), so the sealingmember 5 will not be completely supported, thereby avoiding the situation that the sealingmember 5 cannot be pulled.

在其他实施例中，密封件5也适用于与感光鼓盒分体形成的显影盒，所述显影盒可拆卸地安装至感光鼓盒或电子成像设备。In other embodiments, the sealingmember 5 is also applicable to a developing cartridge formed separately from the photosensitive drum cartridge, and the developing cartridge is detachably mounted to the photosensitive drum cartridge or the electronic imaging device.

本发明涉及的显影盒的组装方法包括如下步骤：The assembling method of developing cartridge that the present invention relates to comprises the following steps:

准备显影壳体的步骤；Steps for preparing the development housing;

安装密封件的步骤；Steps to install the seal;

安装显影辊的步骤。Procedure for installing the developing roller.

本发明采用将密封件焊接或粘接于面向显影剂腔的内侧壁，同时开口的第一端与内侧壁之间的距离大于1mm的技术方案，可以避免密封件无法拉出或显影剂易被带出的情况，从而减少浪费、节约资源，还可以使用户获得更好的使用体验。The present invention adopts the technical scheme that the sealing member is welded or bonded to the inner wall facing the developer chamber, and at the same time, the distance between the first end of the opening and the inner wall is greater than 1 mm, which can prevent the sealing member from being pulled out or the developer from being easily absorbed. Bring out the situation, thereby reducing waste, saving resources, and enabling users to obtain a better experience.
