摘要： In a hybrid development method using a plurality of toner carriers, a development device and image forming apparatus are provided, wherein high image quality in which toner density is not reduced even in the case of high speed printing and the occurrence of development hysteresis (ghost) is controlled is ensured by accelerating the collection of the post-development residual toner on the toner carrier. The counter-charge having occurred in the developer remains in the developer without decreasing to disappear until the developer moves to the second toner carrier on the downstream-side, wherein this counter-charge is caused by supplying toner to the first toner carrier upstream in the rotating direction of the developer carrier.
