PROBLEM TO BE SOLVED: To provide an image forming device capable of continuing image formation for a while even after toner in a toner bottle is used up. SOLUTION: The proposed image forming device is equipped with a toner recycling means 100 which recycles used toner, and a toner end detection means 110 for detecting a toner end state, that is, the end of toner supply. The device improves the ratio of the recycled toner supplied from the toner recycling means 100 to toner which is newly added, right before the toner end detection means 110 detects the toner end state or by the time the toner end state is reset after the toner end. By recycling the used toner in such a manner, image formation can be continued for a while even after the toner in the toner bottle is used up. |
