Developing device, process cartridge, remanufacturing method for developing device and process cartridge

摘要

A remanufacturing method for a developing device and a process cartridge includes a dismounting step of dismounting a regulating member from a development frame member, a cleaning step of cleaning a blade sealing member, and a mounting step of mounting the regulating member to the development frame member after the cleaning step.

主权项

1. A remanufacturing method for a developing device, the developing device including:
a developing roller for developing an electrostatic latent image formed on a photosensitive member by using a developer; a developer accommodating unit configured to accommodate the developer; a regulating member configured to regulate a layer thickness of the developer applied on the developing roller; a development frame member configured to support the regulating member, the development frame member having end sealing members provided at each end side thereof and abutting against a surface of the developing roller to prevent the developer from leaking; and a blade sealing member configured to seal between the regulating member and the development frame member to prevent the developer from leaking, the blade sealing member being configured to be molded by injecting elastomer resin into a seal forming portion of the development frame member and a mold from an injection port thereby contacting each of the end sealing members, the remanufacturing method comprising: (i) dismounting the regulating member from the development frame member; (ii) attaching, to the regulating member, an adhesive member which comes into contact with the blade sealing member when the regulating member is mounted to the development frame member; and (iii) mounting the regulating member to the development frame member so as to sandwich the adhesive member between the blade sealing member and the regulating member.
