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 a hybrid developing method having a plurality of toner carriers, by reducing the decrease in the toner supplying ability to a downstream-side toner carrier, which decrease is caused by the supply of toner to an upstream-side toner carrier on an upstream side in a rotating direction of a 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 a developer layer is stirred.
