Abstract
A developing apparatus for developing a latent image formed on an electrophotographic photosensitive member includes a development member for conveying developer to the electrophotographic photosensitive member to develop the latent image formed on the electrophotographic photosensitive member; a developer storing portion for storing the developer used by the development member to develop the latent image; a developer supplying opening for supplying the developer stored in the developer storing portion, to the development member; and a developer remainder amount reporting member disposed within the developer storing portion, away from the internal surface of the developer storing portion, for reporting the developer remainder amount within the developing apparatus on the basis of the electrostatic capacity between the developer remainder amount reporting member and the development member.
