Abstract
An object of the present invention is to provide a developing apparatus that has a developer carrying body, a first frame having an opening and forming a part of a containing portion for containing the developer, a second frame joined to the first frame to cover the opening, the second frame forming a part of the containing portion, and a sealing member for preventing leakage of the developer from a longitudinal end part of the developer carrying body, the sealing member being supported over the first and second frames, wherein the first and second frames are coupled together in a manner that adjacent surfaces of the first and second frames for supporting the sealing member form substantially identical planes.
Claims14
A developing apparatus comprising:
- a developer carrying body for carrying a developer to develop an electrostatic image formed on an image bearing body by the developer;
- a first frame having an opening and forming a part of a containing portion for containing the developer;
- a second frame joined to said first frame to cover the opening, said second frame forming a part of the containing portion;
- and
- a sealing member for preventing leakage of the developer from a longitudinal end part of said developer carrying body, said sealing member being supported over said first and second frames,
- wherein said first and second frames are coupled together in a manner that adjacent surfaces of said first and second frames for supporting said sealing member form substantially identical planes.
A method for assembling a developing apparatus, comprising steps of:
- joining a first frame having an opening and forming a part of a containing portion for containing developer to a second frame forming a part of the containing portion in a manner that said second frame covers the opening, said joining step causing adjacent surfaces of said first and second frames to form substantially identical planes;
- and
- supporting, over said adjacent surfaces, a sealing member for preventing a developer from leaking through a longitudinal end part of a developer carrying body which carries the developer to develop an electrostatic image on an image bearing body by the developer.
