<p>This invention relates to a developing apparatus, used in an electrophotographic system or an electrographic system for converting an electrostatic image formed on a sensitive material or a dielectric material into a visible image with a one-component developing agent formed solely of a non-magnetic toner (21). The developing apparatus has a carrier roll (24) serving as a movable developing agent carrier which supplies the developing agent to an electrostatic latent image. An elastic coating member (25) presses against the surface of the carrier roll (24) and is supported at one end thereof. The elastic coating member (25) is so directed that its free end is directed opposite the direction of movement of the carrier roll (24). A developing agent container (22) is provided together with a toner stirring member (29) disposed contiguously to or in sliding contact with the carrier roll (24) such that the applied toner (21) is uniformly spread.</p>
