現像装置。[Claims for Utility Model Registration] A developing section that magnetically adsorbs and carries a one-component magnetic developer on the surface of a rotating developer carrier, and is located close to the electrostatic latent image carrier with a predetermined gap. In a developing device of an image forming apparatus that develops an electrostatic latent image carried and conveyed on an electrostatic latent image carrier under the application of DC or DC superimposed pulse bias to the developer carrier, the above-mentioned developer is used. The carrier is placed on the surface of the metal roller,
A magnetic metal mesh magnetized with different polarities on the front and back sides is wound so that one side is in contact with the surface of the metal roller, and the metal mesh is wrapped around a fluorine resin of the same thickness. A developing device characterized in that the developing device is embedded so that the outer surface of the developing device is exposed.
