Method of manufacturing developer container
First Claim
1. A method of manufacturing a developer container including:
- a first frame and a second frame configured to define a developer containing portion;
a first electrode; and
a second electrode which is arranged on a surface of the first frame and which has a surface opposed to the first electrode,wherein a developer amount in the developer containing portion is detected based on a capacitance between the first electrode and the second electrode,the method comprising;
holding a conductive resin member on a mold configured to mold the first frame, a surface of the conductive resin member being directly in contact with a surface of the mold, the surface of the mold being configured to mold a surface of the first frame on a side of the developer containing portion;
injecting a resin to be formed into the first frame, into the mold on which the conductive resin member is held, wherein a position of a gate of injection, with respect to a direction parallel to the surface of the first frame, is different from a position of the conductive resin member;
curing the resin to form the first frame to which the second electrode constituted by the conductive resin member is fixed; and
coupling the first frame and the second frame to form the developer containing portion.

Abstract
A method of manufacturing a developer container including a frame configured to define a developer containing portion, a first electrode, and a second electrode arranged on a surface of the frame and having a surface opposed to the first electrode, a developer amount in the developer containing portion being detected based on a capacitance between the first electrode and the second electrode, the method including: holding a conductive resin member constituting the second electrode on a mold configured to mold the frame, a surface of the conductive resin member being in contact with a surface of the mold configured to mold a surface of the frame on a side of the developer containing portion; injecting a resin to be formed into the frame, into the mold on which the conductive resin member is held; and curing the resin to form the frame to which the second electrode is fixed.

19. A method of manufacturing a developing apparatus including:
-
a first frame and a second frame configured to define a toner chamber, an opening, and a developing chamber; a developer carrying member configured to carry and convey a developer in the developing chamber; a first electrode; and a second electrode, which is arranged on a surface of the first frame and in the toner chamber and which has a surface opposed to the first electrode, wherein the developer is supplied from the toner chamber through the opening to the developing chamber, and wherein a developer amount is detected based on a capacitance between the first electrode and the second electrode, the method comprising; holding a conductive resin member on a mold configured to mold the first frame, a surface of the conductive resin member being directly in contact with a surface of the mold, the surface of the mold being configured to mold a surface of the first frame on a side of the toner chamber; injecting a resin to be formed into the first frame, into the mold on which the conductive resin member is held, wherein a position of a gate of injection, with respect to a direction parallel to the surface of the first frame, is different from a position of the conductive resin member; curing the resin to form the first frame to which the second electrode constituted by the conductive resin member is fixed; and coupling the first frame and the second frame to form the toner chamber, the opening, and the developing chamber. - View Dependent Claims (21, 23)
