Abstract
A developing apparatus is disclosed, in which a developing roller composed of an insulating layer, a dielectric layer and an electrically conductive substrate is made in contact with a photosensitive member to develope a latent image on the member. The dielectric layer is formed of a material whose resistivity-specific dielectricity characteristics satisfies a certain condition which is suitable for medial tone development or binary tone development.
