PROBLEM TO BE SOLVED: To provide an image forming device capable of accurately adjusting image forming conditions that affect an image finally formed on a recording medium. SOLUTION: In the image forming device 100 that forms a toner image and finally fixes the toner image to a recording medium, thereby forming on the recording medium an image composed of the fixed toner image, a toner patch 20 at the intermediate rate of area is formed. When a toner patch 20 is newly formed, the toner patch 20 is formed at the high rate of area in comparison with the previous rate in the case that a toner patch 20 previously measured by an ADC sensor 10 is higher than a target density. |
