Abstract
According to an image forming device according to the disclosure, a required toner amount is calculated based on image data. A toner replenishment device replenishes a development device with toner of a first replenishment amount included in the required toner amount. Toner of the remaining second replenishment amount included in the required toner amount is replenished, based on a toner concentration detection value of a toner concentration sensor. When the image forming device stands continuously unused for a predetermined threshold time or longer, the toner of the second replenishment amount is not replenished during a time period from when an image forming process is started immediately after the unused time, until a specific time elapses.
