PROBLEM TO BE SOLVED: To surely prevent a ghost phenomenon in consequence of a development history, in a developing device of the hybrid developing system. SOLUTION: In this developing device so called the hybrid developing system performing development by adopting the two component developer consisting of magnetic carriers and toner, and feeding only the toner on the developing roll, by independently providing the toner feed developer carrier 3 for feeding the toner to the toner carrier 2 carrying the two component developer, and the toner recovery developer carrier 5 for recovering the toner from the toner carrier 2 carrying the two component developer, the device is allowed to statically recover the toner permitted to pass being carried by the toner carrier 2, in the two component developer carried by the toner recovering developer carrier 5. |
