This application claims priority to Chinese Patent Application No. CN 201910813795.0, filed Sep. 4, 2019, which is hereby incorporated by reference herein as if set forth in its entirety.
The present disclosure relates to developer supply container technology, and particularly to a developer supply container and a developer supply method using the same.
Developer refers to a chemical for making latent images produced by the photosensitive material after exposure to form visible images. From the viewpoint of chemical components, developers can be classified into two major categories of inorganic compounds and organic compounds. The imaging of an image forming apparatus such as a copier or a printer cannot be realized without developer. Generally, the electrophotographic type image forming apparatus such as electrophotographic copiers use fine-particle type developers. In such an image forming apparatus, as a developer is consumed in the image forming process, it is necessary to replenish the developer using a developer supply container.
At present, when injecting the developer into the developer supply container, due to the developer supply container generally has a structure with inner and outer walls, a part of the developer may easily fly into or fall into the gap between the inner wall and the outer wall, which results in loss of the developer, while the smoothness of the movement of the piston member in the developer supply container will also be affected. In addition, when installing a fixing ring of the developer supply container, since the fixing ring is not buckled, there is a certain risk that the fixing ring restores to its original state, and there is also a certain risk that the fixing ring be pulled off. In this case, the piston member in the developer supply container will shake and eventually loosen, which will cause defection of product. Simultaneously, when assembling the piston member in the developer supply container after replenishing the developer into the developer supply container, due to the interior of the developer supply container is a sealed environment, there is great difficulty in installing the piston member in the developer supply container. Hence, it is a necessary to propose a new type of developer supply container to solve the problems in the prior art.
An object of the present disclosure is to provide a developer supply container and a developer supply method using the same to solve the above-mentioned problems in the prior art that, at present, when injecting the developer into the developer supply container, due to the developer supply container generally has a structure with inner and outer walls, a part of the developer may easily fly into or fall into the gap between the inner wall and the outer wall, which results in loss of the developer, while the smoothness of the movement of the piston member in the developer supply container will also be affected. In addition, when installing a fixing ring of the developer supply container, since the fixing ring is not buckled, there is a certain risk that the fixing ring restores to its original state, and there is also a certain risk that the fixing ring be pulled off. In this case, the piston member in the developer supply container will shake and eventually loosen, which will cause defection of product. Simultaneously, when assembling the piston member in the developer supply container after replenishing the developer into the developer supply container, due to the interior of the developer supply container is a sealed environment, there is great difficulty in installing the piston member in the developer supply container.
