## Abstract

There is provided a manufacturing method of manufacturing a cartridge by using a cartridge having a rotator, a frame that supports the rotator, an elastic member that is provided in a concave portion formed in the frame along a rotation axis direction of the rotator, and a sheet member that has one end fixed to the elastic member and the other end abutting on the rotator along the rotation axis direction of the rotator, and the manufacturing method includes: detaching the rotator from the frame; detaching the sheet member from the frame; detaching the elastic member from the frame; and attaching another sheet member to the frame via an adhesive member that is attached to an adhesive member attachment portion formed in the concave portion of the frame.

## Claims

### Claim 1

A method of manufacturing a cartridge that is attachable to an image forming apparatus by using a cartridge having a rotator, a frame that supports the rotator, an elastic member that is provided in a concave portion formed in the frame along a rotation axis direction of the rotator, and a sheet member that has one end portion fixed to the elastic member and another end portion abutting on the rotator along the rotation axis direction of the rotator, the manufacturing method comprising:
detaching the rotator from the frame;
detaching the sheet member from the frame;
detaching at least a part of the elastic member from the frame; and
attaching another sheet member to the frame via an adhesive member that is attached to an adhesive member attachment portion formed between the concave portion and the another sheet member.

### Claim 2 (depends on 1)

The manufacturing method according to claim 1, wherein the adhesive member attachment portion is provided in both sides of the concave portion in a direction orthogonal to a rotational axis of the rotator.

### Claim 3 (depends on 1)

The manufacturing method according to claim 1, wherein the adhesive member attachment portion is formed in advance in the frame before reproduction.

### Claim 4 (depends on 1)

The manufacturing method according to claim 1, wherein the adhesive member is a sticky material.

### Claim 5 (depends on 4)

The manufacturing method according to claim 4, wherein the adhesive member is a double-sided adhesive tape that includes the sticky material.

### Claim 6 (depends on 1)

The manufacturing method according to claim 1, wherein the adhesive member is a liquid adhesive member.

### Claim 7 (depends on 1)

The manufacturing method according to claim 1, wherein the adhesive member is configured separately from the another sheet member, and the manufacturing method further comprises:
attaching the adhesive member to the adhesive member attachment portion; and
sticking the another sheet member to the adhesive member.

### Claim 8 (depends on 1)

The manufacturing method according to claim 1, wherein the attaching of the another sheet member is performed with the adhesive member after the another sheet member is integrated with the adhesive member.

### Claim 9 (depends on 1)

The manufacturing method according to claim 1, wherein the elastic member is molded by injecting an elastic resin from an inlet of the frame into a molding space formed by causing a mold to abut on the frame.

### Claim 10 (depends on 1)

The manufacturing method according to of claim 1, wherein when the sheet member is peeled from the frame, the elastic member is detached from the frame integrally with the sheet member in a state in which the elastic member is attached to a side of the sheet member.

### Claim 11 (depends on 1)

The manufacturing method according to claim 1, wherein the rotator is an image carrier, the frame has a cleaning container that accommodates developer removed from the image carrier, and the sheet member and the another sheet member are flexible sheet members that abut on the image carrier to prevent leakage of the developer from between the cleaning container and the image carrier to outside of the cartridge.

### Claim 12 (depends on 1)

The manufacturing method according to claim 1, wherein the rotator is a developer carrier that carries and transports developer, the frame has a developing container that accommodates the developer supplied to an image carrier, and the sheet member and the another sheet member are flexible sheet members that abut on the developer carrier to prevent leakage of the developer from between the developing container and the developer carrier to the outside of the cartridge.

### Claim 13

A method of manufacturing a cartridge that is attachable to an image forming apparatus by using a cartridge having a rotator, a frame that supports the rotator, an elastic member that is provided in a concave portion formed in the frame along a rotation axis direction of the rotator, and a sheet member that has one end portion fixed to the elastic member and another end portion abutting on the rotator along the rotation axis direction of the rotator, the manufacturing method comprising:
detaching the rotator from the frame;
detaching the sheet member from the frame;
detaching the elastic member from the frame;
filling at least part of the concave portion with a filling member; and
sticking another sheet member with an adhesive member via the filling member.

### Claim 14 (depends on 13)

The manufacturing method according to claim 13, wherein the filling member is a thermoplastic resin.

### Claim 15 (depends on 13)

The manufacturing method according to claim 13, wherein the filling member is constituted by the adhesive member.

### Claim 16

A method of manufacturing a cartridge that is attachable to an image forming apparatus by using a cartridge having a rotator, a frame that supports the rotator, an elastic member that is provided in a concave portion formed in the frame along a rotation axis direction of the rotator, and a sheet member that has one end portion fixed to the elastic member and another end portion abutting on the rotator along the rotation axis direction of the rotator, the manufacturing method comprising:
detaching the rotator from the frame;
detaching the sheet member from the frame;
detaching the elastic member from the frame; and
attaching another sheet member to surfaces provided on both sides of the concave portion in a direction orthogonal to a rotation axis of the rotator via an adhesive member.

### Claim 17 (depends on 16)

The manufacturing method according to claim 16, wherein the adhesive member and the another sheet member are attached so as to cover at least part of the concave portion.

### Claim 18 (depends on 16)

The manufacturing method according to claim 16, wherein a thickness of the another sheet member attached to the surfaces is different from the sheet member detached from the frame.
