显影剂容器，显影装置，处理盒，图像形成装置和图像形成装置的装置主体

Developer container, developing apparatus, process cartridge, image forming apparatus, and apparatus main body of image forming apparatus
Abstract:
A developing apparatus includes: a developing chamber that has a developer bearing member bearing developer, an accommodating chamber that has a concave portion and an opening and accommodates the developer under the developing chamber, a conveying member that conveys the developer by rotation; and a first detecting member and a second detecting member that detect an amount of the developer in use of capacitance. A part of the concave portion is within a turning radius of the conveying member. In addition, the first detecting member is provided on a downstream side in a rotating direction of the conveying member relative to the concave portion, and the second detecting member is provided on an upstream side in the rotating direction of the conveying member relative to the concave portion.
