摘要： Provided is a development device and an image forming apparatus that realize high image quality with improved decrease in density at high speed development and with reduced occurrence of development hysteresis (ghost) in the hybrid developing method having a plurality of toner carriers, by reducing the decrease in the toner supplying ability to the downstream-side toner carrier, which decrease is caused by the supply of toner to the toner carrier on the upstream side in the rotating direction of the developer carrier. By providing a magnetic pole between main magnetic poles, of the developer carrier, facing the toner carriers, a magnetically raised bristle of developer is moved by a magnetic force, while the developer in which development hysteresis due to supplying toner to the upstream-side toner carrier occurred is conveyed to supply toner to the downstream-side toner carrier, whereby the developer layer is stirred.

摘要： A development apparatus and an image forming apparatus capable of minimizing deterioration of a carrier for a long time, even in a case of continuous formation of images of a smaller image area ratio. The charging of toner is assisted by using a developer composed of a mixture of toner and the carrier, to the surface of which is added a reverse polarity particle having a polarity reverse to that of a charged toner. Separation of the toner or reverse polarity particle of the developer prior to a process of development prevents the reverse polarity particle from being consumed in a developing area, whereby an effect thereof is maintained for a long time.
