Remanufacturing method of developer accommodating unit

1. A remanufacturing method of a developer accommodating unit including a flexible container configured to accommodate developer and provided with a plurality of openings for discharging the developer into a frame member, the frame member configured to accommodate the flexible container and a developer bearing member, the remanufacturing method comprising:

removing the developer bearing member from the developer accommodating unit, and

refilling developer between the frame member and the flexible container.

2. The remanufacturing method according to claim 1 , wherein refilling includes compressing the flexible container inside the frame member, before or when refilling the developer, to make a capacity of the flexible container smaller than a capacity of the flexible container filled with the developer.

3. The remanufacturing method according to claim 1 , wherein the developer accommodating unit further includes a sealing member configured to seal the plurality of openings and to expose the plurality of openings when the sealing member is moved, and an unsealing member attached to the sealing member and configured to move the sealing member to unseal the plurality of openings, the remanufacturing method further comprising removing the unsealing member from the developer accommodating unit.

4. The remanufacturing method according to claim 1 , wherein the developer accommodating unit further includes a sealing member configured to seal the plurality of openings and to expose the plurality of openings when the sealing member is moved, and an unsealing member attached to the sealing member and configured to move to unseal the plurality of openings, the remanufacturing method further comprising separating at least a part of the sealing member from the frame member.

5. The remanufacturing method according to claim 4 , wherein separating at least a part of the sealing member from the frame member includes cutting off the sealing member at a portion other than an engaged portion engaged with the unsealing member.

6. The remanufacturing method according to claim 4 , wherein separating at least a part of the sealing member from the frame member includes disengaging an engaged portion engaged with the unsealing member.

7. The remanufacturing method according to claim 1 further comprising forming a formed hole on the frame member,

wherein refilling includes filling the developer through the formed hole.

8. The remanufacturing method according to claim 1 , further comprising processing a communication hole for refilling the developer into the frame member.

9. The remanufacturing method according to claim 7 , wherein refilling the developer includes directly filling the developer into the frame member.

10. The remanufacturing method according to claim 2 , wherein, to reduce a capacity of the flexible container, compressing includes injecting air between the frame member and the flexible container.

11. The remanufacturing method according to claim 2 , wherein, to reduce a capacity of the flexible container, compressing includes inserting a flaring member at a position of the flexible container and expanding the flaring member while pushing the flexible container.

12. A developing device remanufacturing method of a developing device including the developer accommodating unit remanufactured by the remanufacturing method according to claim 1 , wherein the developer bearing member is configured to develop an electrostatic image formed on an image bearing member, the developing device remanufacturing method comprising:

attaching the developer bearing member to the frame member.

13. A process cartridge remanufacturing method of a process cartridge including the developer accommodating unit remanufactured by the remanufacturing method according to claim 1 , wherein the developer bearing member is configured to develop an electrostatic image formed on an image bearing member, the process cartridge remanufacturing method comprising:

attaching the image bearing member to the frame member.

14. A image forming apparatus remanufacturing method of an image forming apparatus including the developer accommodating unit remanufactured by the remanufacturing method according to claim 1 , wherein the developer bearing member is configured to develop an electrostatic image formed on an image bearing member, the image forming apparatus remanufacturing method comprising:

attaching the image bearing member to the frame member.
