Zusammenfassung: | Provided is a development device and an image forming apparatus both using a hybrid development method and capable of forming high quality images without occurrence of development hysteresis (ghost). The nip portion of the toner carrier and the developer carrier is configured as follows: the rotating direction of a toner carrier and a developer carrier are in counter directions; a magnetic pole facing the toner carrier is positioned on the upstream side in the developer carrier rotating direction; and a counter charge generated by the toner supply reaches a toner recovering portion without being considerably attenuated. |
