PROBLEM TO BE SOLVED: To provide an image forming device configured to improve accuracy of color registration.SOLUTION: An image forming device 1 includes: base density acquiring means 404 that acquires base density for one turn of an intermediate transfer belt B1 during color calibration; stained portion detecting means 405 that compares the acquired base density with a predetermined set threshold, to detect a portion of the intermediate transfer belt B1 corresponding to the position acquiring the base density exceeding the threshold, as a stained portion; and color registration means 406 that forms a color registration patch pattern in a portion of the intermediate transfer belt B1, which is different from the detected stained portion and allows the color registration patch pattern to be formed, to executed color registration. |
