Abstract

Provided is a remanufacturing method of a developer accommodating unit including a flexible container provided with an opening and configured to accommodate developer, and a frame member configured to accommodate the flexible container. The remanufacturing method includes refilling the developer into the flexible container.

First claim

What is claimed is:

1. A remanufacturing method of a cartridge including a photosensitive unit and a developing unit, wherein the photosensitive unit comprises an image bearing member, and wherein the developing unit comprises a developer bearing member; a flexible container configured to accommodate developer and provided with a plurality of openings for discharging the developer into a frame member; and the frame member configured to accommodate the flexible container, the remanufacturing method comprising:
separating the photosensitive unit and the developing unit; and
refilling developer into the frame member.

2. The remanufacturing method according to claim 1 , wherein the refilling comprises refilling developer into the flexible container inside the frame member.

3. The remanufacturing method according to claim 1 , further comprising:
processing a frame member communication hole on the frame member.

4. The remanufacturing method according to claim 3 , further comprising communication hole sealing for sealing the frame member communication hole.

5. The remanufacturing method according to claim 2 , wherein the refilling comprises refilling developer through at least one of the plurality of openings.

6. The remanufacturing method according to claim 2 , further comprising:
processing a container communication hole on the flexible container,
wherein the refilling refills developer into the flexible container inside the frame member through at least one of the container communication hole and one of the plurality of openings.

7. The remanufacturing method according to claim 1 , further comprising attaching a sealing member to the plurality of openings of the flexible container to reseal at least one of the plurality of openings.

8. The remanufacturing method according to claim 1 , further comprising deforming the flexible container.

9. The remanufacturing method according to claim 8 , wherein at least one of the plurality of openings is deformed.

10. A remanufacturing method of a developer accommodating unit including a sheet member, a rotatable member attached to the sheet member, a flexible container configured to accommodate developer and provided with an opening for discharging the developer into a frame member, and the frame member configured to accommodate the flexible container, the rotatable member, and the sheet member, the remanufacturing method comprising:
refilling developer into the flexible container inside the frame member.

11. The remanufacturing method according to claim 10 , wherein the flexible container is provided with a plurality of the openings.

12. The remanufacturing method according to claim 10 , wherein the remanufacturing method further comprises removing at least a part of the sheet member.

13. The remanufacturing method according to claim 10 , wherein the remanufacturing method further comprises removing at least a part of the rotatable member.

14. The remanufacturing method according to claim 11 , further comprising processing a frame member communication hole on the frame member.

15. The remanufacturing method according to claim 14 , further comprising communication hole sealing for sealing the frame member communication hole.

16. The remanufacturing method according to claim 11 , wherein the refilling comprises refilling developer through at least one of the plurality of openings.

17. The remanufacturing method according to claim 11 , further comprising:
processing a container communication hole on the flexible container,
wherein the refilling refills developer into the flexible container inside the frame member through at least one of the container communication hole and one of the plurality of openings.

18. The remanufacturing method according to claim 11 , further comprising attaching a sealing member to the plurality of openings of the flexible container to reseal at least one of the plurality of openings.

19. The remanufacturing method according to claim 11 , further comprising deforming the flexible container.

20. The remanufacturing method according to claim 19 , wherein at least one of the plurality of openings is deformed.

21. A flexible container used for a remanufactured developing device comprising:
an accommodating portion for accommodating developer, the accommodating portion provided with a plurality of openings for discharging the developer,
wherein the accommodating portion is accommodated inside a frame member of the remanufactured developing device, and
wherein the remanufactured developing device includes:
a developer bearing member for bearing the developer;
the flexible container for accommodating the developer; and
the frame member accommodating the developer bearing member and the flexible container.

22. A manufacturing method of a flexible container used for a remanufactured developing device comprising:
filling developer into the flexible container, the flexible container provided with a plurality of openings for discharging the developer,
wherein the flexible container is accommodated inside a frame member of the remanufactured developing device, and
wherein the remanufactured developing device includes:
a developer bearing member for bearing the developer;
the flexible container for accommodating the developer; and the frame member accommodating the developer bearing member and the flexible container.
