PROBLEM TO BE SOLVED: To provide an image forming device constituted so that a desired additive can be mixed in even when the quantity of recovery toner is increased because the flowability of toner or developer is lowered at a toner recycling time. SOLUTION: This image forming device is provided with a recovery hopper 8b recovering and housing the toner used for making an electrostatic latent image formed on an image carrier 1 into a toner image by a developing device 4 and left one the carrier 1 after transferring the toner image onto a transfer paper and a carrying device 11 carrying the toner to a developing unit from the hopper 8b. Then, the upper part of the hopper 8b is provided with an additive hopper 12 so that the additive is mixed in the recovery toner by the rotation of a additive replenishment roller 12a. |
