PROBLEM TO BE SOLVED: To provide an image forming apparatus that can reduce the downtime of the image forming apparatus, while reliably executing a necessary supply mode and reducing the frequency at which an unnecessary supply mode is executed to avoid an excessive reduction in toner density.SOLUTION: A control unit 100 releases the inhibition of image forming operation when a toner bottle 70 is replaced, and permits the image forming operation during a period until an accumulated value Vsum of a video count value reaches a predetermined amount irrespective of a detection result of an inductor sensor 26. When the accumulated value Vsum has reached the predetermined value, if a detection result of the inductor sensor 26 is less than 7.5%, which is defined between a target toner density 8% and an NG toner density 6.5%, the control unit 100 inhibits image formation and supplies toner to a developing device 2 for 10 seconds. |
