うにしたことを特徴とする乾式現像装置。In the developing section, a movable developer holder is disposed facing the electrostatic latent image bearing surface with a predetermined gap therebetween, and is made of a non-magnetic cylindrical body having a magnet inside. a wedge-shaped space that is located between the developer supply means and the developing section, contacts the surface of the developer holder, and opens in the direction of the developer supply means from the contact point. The invention is characterized in that it has an elastic triboelectric charging member disposed so as to form a layer, and the layer thickness of the developer is controlled by bringing an edge portion of one end of the tribocharging member into pressure contact with the developer holder. A dry developing device.
