A developing device and image forming apparatus are provided, wherein high quality images, in which generation of development hysteresis is alleviated, are obtained over a long period using a hybrid development method including a toner-supplying developer supporting member and a toner-collecting developer supporting member. The gate structure is disposed on a surface of the silicon substrate. The liquids may be applied by a dispenser or an ink jet printer. An inductive well 22 can be formed to provide a platform for the formation of inductive devices 34 within an inductive region 26.
