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, the cartridge comprising a flexible container and detachably mountable to an image forming apparatus, the remanufacturing method comprising:
filling a used flexible container with developer, the used flexible container being configured to accomodate developer and provided with a plurality of openings for discharging developer; and
attaching a sealing member to an outside surface of the used flexible container such that the sealing member covers the plurality of openings.

2. The remanufacturing method according to claim 1 , wherein the used flexible container comprises a developer accommodating portion for accommodating developer, and the used flexible container is deformable to change a capacity of the developer accommodating portion.

3. The remanufacturing method according to claim 1 , wherein the remanufacturing method comprises removing at least part of a frame member for accommodating the used flexible container such that at least part of the used flexible container is exposed.

4. The remanufacturing method according to claim 1 , wherein the used flexible container is a flexible container with developer consumed.

5. The remanufacturing method according to claim 1 , wherein the remanufacturing method comprises attaching an image bearing member for bearing a latent image to the cartridge.

6. The remanufacturing method according to claim 1 , wherein the remanufacturing method comprises attaching a developer bearing member for developing a latent image to the cartridge.

7. A cartridge detachably mountable to an image forming apparatus comprising:
an used flexible container configured to accommodate developer and provided with a plurality of openings for discharging developer;
developer filled in the used flexible container; and
a sealing member bonded to an outside of the used flexible container such that the plurality of the openings are covered by the sealing member.

8. The cartridge according to claim 7 , wherein the used flexible container comprises a fixed portion being provided with a plurality of the holes.

9. The cartridge according to claim 7 , wherein the used flexible container comprises a developer accommodating portion for accommodating developer, and the used flexible container is deformable to change a capacity of the developer accommodating portion.

10. The cartridge according to claim 7 , wherein the used flexible container is a flexible container with developer consumed.

11. The cartridge according to claim 7 , wherein the cartridge includes an image bearing member for bearing a latent image.

12. The cartridge according to claim 7 , wherein the cartridge includes a developer bearing member for developing a latent image.

13. A cartridge detachably mountable to an image forming apparatus comprising:
developer filled in an used flexible container being configured to accommodate developer and provided with a plurality of openings for discharging developer,
wherein the plurality of the openings are covered by a sealing member bonded to an outside of the used flexible container.

14. The cartridge according to claim 13 , wherein the used flexible container comprises a fixed portion being provided with a plurality of holes.

15. The cartridge according to claim 13 , wherein the used flexible container comprises a developer accommodating portion for accommodating developer, and the used flexible container is deformable to change a capacity of the developer accommodating portion.

16. The cartridge according to claim 13 , wherein the used flexible container is a flexible container with developer consumed.

17. The cartridge according to claim 13 , wherein the cartridge includes an image bearing member for bearing a latent image.

18. The cartridge according to claim 13 , wherein the cartridge includes a developer bearing member for developing a latent image.
