PROBLEM TO BE SOLVED: To provide an image forming device constituted so that a warm up time may be shortened by rotating a fixing device and reducing a period having a low pitch in terms of temperature increase. SOLUTION: The image forming device is provided with a 1st motor 21 for rotating a photoreceptor 3, a 2nd motor 20 for rotating both of a heat roll and a developing roll 16, a warm up means 23 for heating the fixing device 10 up to a prescribed temperature, and an image control means 22 equipped with a density sensor 13 for measuring the density of a toner image, and for measuring the density of a reference toner image and adjusting an image forming parameter, the 1st measurement of measuring the base density of the reference toner image in a state where the 1st motor 21 is rotated but the rotation of the 2nd motor 20 is stopped, and the 2nd measurement of measuring the density after forming the reference toner image in a state where the 1st motor 21 and also the 2nd motor 20 are rotated are performed by the image control means 22. |
