Developer container, developing container, developing device, process cartridge, side cover, bearing structrue, and image forming apparatus

A developing container to be connected to a developer container that includes:

• a developer containing portion for containing a developer, a developer supply opening, and a sealing member that seals the developer supply opening, the developing container comprising:
• a developer bearing member for acting on an electrophotographic photosensitive member of an image forming apparatus;
• a developing container main body that supports the developer bearing member;
• and
• a grip member for pulling out the sealing member in a longitudinal direction of the developer container,
• wherein the developing container main body and the grip member are integrally molded from resin materials having low compatibility to be separable from each other, and
• the grip member has a longitudinal dimension extending to an outside of a developing container mounting region of the image forming apparatus.

A bearing structure of a developing device that is provided with:

• a developer container having a developer containing portion that contains a developer, a developer supply opening, and a sealing member that seals the developer supply opening, and a developer bearing member for acting on an electrophotographic photosensitive member of an image forming apparatus, the bearing structure comprising:
• a bearing member that rotatably supports the developer bearing member;
• and
• a grip member for pulling out the sealing member in a longitudinal direction of the developer container,
• wherein the bearing member and the grip member are integrally molded from resin materials having low compatibility to be separable from each other, and
• the grip member has a longitudinal dimension extending to an outside of a developing device mounting region of the image forming apparatus.

A side cover of a developing device having a developer container that includes:

• a developer containing portion for containing a developer, a developer supply opening;
• and a sealing member that seals the developer supply opening, the side cover comprising:
• a side cover main body connected to a side surface of the developer container;
• and
• a grip member for pulling out the sealing member in a longitudinal direction of the developer container,
• wherein the side cover main body and the grip member are integrally molded from resin materials having low compatibility to be separable from each other, and
• the grip member has a longitudinal dimension extending to an outside of a developing device mounting region of the image forming apparatus.
