1. A developer container configured to accommodate developer comprising:
- a stirring member having a sheet member for stirring the developer; and
a conductive resin sheet arranged in the developer container so as to come into contact with the sheet member for detecting an amount of developer by using electrostatic capacitance, whereinan end of the conductive resin sheet in a longitudinal direction is provided outside an end of the sheet member in a longitudinal direction.

Abstract
This disclosure provides a developer container in which a conductive resin sheet is used as an electrode for detecting an amount of developer by using electrostatic capacitance. A configuration in which an end of the conductive resin sheet in a longitudinal direction is provided outside an end of a sheet member in a longitudinal direction, or a configuration in which the sheet member starts contact with the conductive resin sheet from a second surface on the downstream side in a direction or rotation than a first surface are also provided.

7. A developer container configured to accommodate developer comprising:
-
a stirring member having a sheet member for stirring the developer; and a conductive resin sheet arranged so as to come into contact with the sheet member when the stirring member rotates for detecting an amount of developer by using electrostatic capacitance, wherein the conductive resin sheet includes at least a first surface as a side surface located on the upstream side of the stirring member in a direction of rotation thereof, and a second surface configured to be capable of coming into contact with the developer, and at the time of rotating and coming into contact with the conductive resin sheet, one end of the sheet member is configured to start contact with the conductive resin sheet from the second surface located on the downstream side of the first surface in the direction of rotation.
