徴とする現像装置。[Claim for Utility Model Registration] A developer carrier that rotates in pressure contact with an electrostatic latent image carrier that rotates at a constant speed, and a one-component non-magnetic insulating developer that is rubbed between the developer carrier and this developer carrier. A triboelectric charging member is provided, and the triboelectrically charged one-component non-magnetic insulating developer is conveyed to a pressure contact portion with the electrostatic latent image carrier by rotation of the developer carrier to carry the electrostatic latent image. In a developing device for developing an electrostatic latent image on a body, the developer carrier is a roller comprising a central shaft, an intermediate layer made of a porous foam, and an elastic surface layer, and the developer carrier A developing device characterized in that the frictional charging member is curved and pressed against the outer periphery of the surface layer.
