Abstract
A developer container is manufactured in which, in molding, a recess is disposed in an area in which a confluence in which first resin poured from a first inlet and second resin poured from a second inlet merge is formed.
Claims6
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.
