1. A manufacturing method for a developer container capable of detecting a developer amount using a change in electrostatic capacitance between a first electrode and a second electrode, comprising:
- holding a first resin sheet, which will become the first electrode, to a first area of a mold and a second resin sheet, which will become the second electrode, to a second area of the mold, the second resin sheet including a recess in such that the recess is located at a position that faces a longitudinal end portion of the first resin sheet; and
molding the developer container which includes the first resin sheet and the second resin sheet by pouring resin in from a first inlet of the mold and a second inlet of the mold,wherein the recess is disposed in an area in which a confluence is formed by the merging of the resin poured from the first inlet and the resin poured from the second inlet.

7. A developer container capable of detecting a developer amount using a change in electrostatic capacitance between a first electrode and a second electrode, comprising:
-
a first resin sheet serving as the first electrode; a second resin sheet which has a recess and serves the second electrode; and a rotatable conveyance member which has a sheet-shaped conveying portion for conveying developer, wherein the first resin sheet and the second resin sheet are disposed in a such manner that the recess is located at a position which faces an end portion of the first resin sheet, and wherein a distance from a longitudinal end portion of the first resin sheet to the second resin sheet in an end portion of the first resin sheet near the second resin sheet is shorter than a distance from a bottom portion of the recess of the second resin sheet to the first resin sheet. - View Dependent Claims (8, 9, 10, 11)
