Abstract
A developer container includes a stirring member that stirs a developer and a conductive resin sheet that comes into contact with the stirring member when the stirring member rotates. The developer container detects developer quantity using capacitance.
Claims20
A developer container configured to accommodate a developer, the developer container comprising:
- a stirring member configured to stir the developer;
- and
- a conductive resin sheet disposed so as to come into contact with the stirring member when the stirring member rotates and configured to detect developer quantity using capacitance,
- wherein at least part of a side face of the conductive resin sheet situated on the upstream side thereof in the direction of rotation of the stirring member is fixed to the developer container.

A developer container configured to accommodate a developer, the developer container comprising:
- a stirring member configured to stir the developer;
- and
- a conductive resin sheet disposed so as to come into contact with the stirring member when the stirring member rotates and configured to detect developer quantity using capacitance,
- wherein a first side face, which is a side face of the conductive resin sheet situated on the upstream side thereof in the direction of rotation of the stirring member, and a second side face, which is a side face of the developer container, are provided facing one another,
- and wherein a distance from a first side face portion, which is the portion of the conductive resin sheet that is at the closest distance from a stirring axis of the stirring member to the stirring axis, is the same distance or longer than a distance from a second side face portion, which is the portion of the developer container at the closest distance from the stirring axis to the stirring axis.
