PURPOSE:To sufficiently spread toner to a toner replenishing tank when no toner state of the toner replenishing tank is released. CONSTITUTION:When the image forming device is stopped due to the toner in the toner replenishing tank 2 being empty, this no toner state is stored. When a power source is turned ON after the toner is replenished to the toner replenishing tank 2, the state before stopping is called. If there is no toner, toner carrying action is carried out inside the toner replenishing tank 2 to spread the toner. After that, adjustment of the toner concentration is carried out based on output of a toner concentration sensor 7. |
