Abstract

PURPOSE:To obtain a vivid picture and improve the reliability, by interposing a nonferromagnetic substance and conductive netlike material between a recording material and a magnet such as a magnetic roll and providing a developer supplying means for a developer vessel or the like around the magnet. CONSTITUTION:A conductive netlike material supporting member 16 is provided near the lower part of a magnetic roll 3 and in the part opposite to a developer vessel 4, and a netlike material 17 consisting of high-permeability nonferromagnetic substance and conductive materials such as aluminum and stainless steel is supported between this supporting member 16 and the developer vessel 4, and this netlike material 17 is placed between the magnetic roll 3 and a dielectric layer 1a of a recording paper. Thus, a high-reliability developing device is obtained where the developer is carried stably to obtain a vivid picture.
