摘要：
In a scavengeless development apparatus, an electrode wire is disposed between a donor roll and a latent image to form a powder cloud of toner to develop the latent image. A magnet is disposed along the electrode wire, and low-frequency AC is passed through the electrode wire. The electromagnetic forces acting on the wire from the interaction of the AC with the magnetic field are adapted substantially to cancel mechanical vibration of the electrode wire.
