1. A development device which is removably insertable into an image forming apparatus, the development device comprising:

  • a housing configured to store developer;

    a developer carrying member configured to carry developer;

    a first conductive member having a first surface for use in detection of an amount of developer stored in the housing based on a change in electrostatic capacitance, the first conductive member extending in a lengthwise direction of the developer carrying member;

    a second conductive member having a second surface facing the first surface, the second conductive member extending in the lengthwise direction of the developer carrying member;

    a development contact point electrically connected to the developer carrying member;

    a first contact point electrically connected to the first conductive member; and

    a second contact point electrically connected to the second conductive member,wherein the first contact point is disposed on a more inner side than the development contact point in a perpendicular direction with respect to an insertion direction, the insertion direction being a direction in which the development device is inserted into the image forming apparatus, andwherein the second contact point is disposed on a more inner side than the first contact point in the perpendicular direction with respect to the insertion direction.
