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.
Claims17
A cartridge comprising:
- a rotator;
- a frame for storing developer, the frame supporting the rotator such that the rotator is rotatable, the frame including a first surface provided with a concave portion, the concave portion including a bottom portion, and the bottom portion including a second surface that is furthest from the first surface with respect to a direction perpendicular to the first surface;
- a sheet member adjacent to the first surface and including an end portion abutting on the rotator so as to prevent leakage of the developer to outside of the frame from a first gap formed between the rotator and the frame, and
- an adhesive member for attaching the sheet member to the frame, the adhesive member being disposed so as to cover at least part of the concave portion, and the adhesive member attached to the frame such that the adhesive member faces the second surface with a second gap being formed between the adhesive member and the second surface.

- and
- a filling member filling at least part of the concave portion, the filling member attached to the frame such that the filling member faces the second surface with a second gap being formed between the filling member and the second surface,
- wherein the sheet member is attached to the filling member.
