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 used developer accommodating unit including a flexible container provided with an opening sealed by a sealing member and configured to accommodate developer, and a frame member configured to accommodate the flexible container, the remanufacturing method comprising:
refilling the developer into the flexible container.

2 . The remanufacturing method according to claim 1 , wherein the refilling comprises refilling the developer from the outside of the frame member.

3 . The remanufacturing method according to claim 2 , further comprising:
processing a frame member communication hole on the frame member; and container processing for processing a container communication hole on the flexible container, wherein the refilling refills the developer into the flexible container inside the frame member through the frame member communication hole and the container communication hole.

4 . The remanufacturing method according to claim 3 , further comprising communication hole sealing for sealing at least either one of the frame member communication hole and the container communication hole to seal the developer refilled in the flexible container.

5 . The remanufacturing method according to claim 3 , wherein the container communication hole is larger than the opening.

6 . The remanufacturing method according to claim 1 , further comprising attaching a sealing member to the opening of the flexible container to reseal the opening.

7 . The remanufacturing method according to claim 2 , further comprising frame member processing for processing a frame member communication hole on the frame member,
wherein the refilling refills the developer into the flexible container inside the frame member through the frame member communication hole and the opening.

8 . The remanufacturing method according to claim 1 , further comprising injecting compressed air into the flexible container.

9 . The remanufacturing method according to claim 1 , wherein the refilling comprises refilling the developer through the opening of the flexible container.

10 . The remanufacturing method according to claim 9 , wherein the developer accommodating unit further includes a sealing member configured to seal the opening and to expose the opening when moved, and an unsealing member attached to the sealing member and operable to move to unseal the opening, and
wherein the remanufacturing method further comprises removing at least a part of the sealing member before the refilling.

11 . The remanufacturing method according to claim 10 , wherein the sealing member has a perforation.

12 . The remanufacturing method according to claim 10 , wherein the sealing member includes a sealing portion configured to close the opening, and a fixing portion configured to be fixed to the unsealing member, and
wherein the sealing portion and the fixing portion are adhered to each other.

13 . The remanufacturing method according to claim 10 , wherein the sealing member has a thinner film thickness at a portion at which the unsealing member is fixed than a film thickness at a portion at which the opening of the flexible container is sealed.

14 . The remanufacturing method according to claim 10 , wherein a frame member communication hole is formed on the frame member, and at least the sealing member is removed through the frame member communication hole.

15 . The remanufacturing method according to claim 10 , wherein a frame member communication hole is formed on the frame member, at least the sealing member is removed through the frame member communication hole, and the developer is refilled into the flexible container through the frame member communication hole and the opening.

16 . The remanufacturing method according to claim 9 , further comprising processing the opening so as to enlarge the opening, before the refilling.

17 . The remanufacturing method according to claim 16 , wherein a plurality of openings are provided.

18 . The remanufacturing method according to claim 16 , wherein the least one of the plurality of the openings is processed so as to enlarge the opening, before the refilling.

19 . The remanufacturing method according to claim 16 , wherein the opening is processed to connect the plurality of the openings.

20 . The remanufacturing method according to claim 16 , wherein the opening is processed to form an opening larger than an area that includes all of a plurality of the openings.

21 . The remanufacturing method according to claim 2 , further comprising processing, on the flexible container, another opening different from the opening before the refilling.

22 . The remanufacturing method according to claim 21 , wherein the developer accommodating unit further includes a sealing member configured to seal the opening and to expose the opening when being moved, and an unsealing member attached to the sealing member and configured to move to unseal the opening, and
wherein the remanufacturing method further comprises removing at least a part of the sealing member before the refilling.

23 . The remanufacturing method according to claim 21 , wherein the developer accommodating unit is a developer accommodating unit in which a regulating member for regulating a layer thickness of the developer on a developer bearing member is attached to the frame member, and
wherein the remanufacturing method further comprises separating only the regulating member from the frame member before the another opening processing.

24 . The remanufacturing method according to claim 21 , wherein the another opening is processed to be larger than the opening.

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

26 . A remanufacturing method of a cartridge including an image bearing member, a developer bearing member configured to develop an electrostatic image formed on the image bearing member, and a developer accommodating unit remanufactured by the remanufacturing method according to claim 1 .

27 . A remanufacturing method of an image forming apparatus including an image bearing member, a developer bearing member configured to develop an electrostatic image formed on the image bearing member, and a developer accommodating unit remanufactured by the remanufacturing method according to claim 1 .

28 . 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 comprising:
refilling the developer after forming a cut portion or a through hole on the flexible container.
