PROBLEM TO BE SOLVED: To provide a test image, a test image forming system, a test image forming method, a test image forming program, a storage medium, an abnormal recording element detection system, an abnormal recording element detection method, an abnormal recording element detection program, and a storage medium, capable of detecting an abnormal recording element which is a problem in image recording in abnormal recording element detection using the test image.SOLUTION: A test image is formed based on input data in such a manner that a recording head and a recording medium are moved relative to each other, a plurality of recording elements selected for every other N (N is integer of 1 or more) in a projection recording element (507) is set as a first recording element, a recording element unselected as a first recording element is set as a second recording element, a first-stage pattern (508-1) is formed based on a second input gradation value in the recording area of the second recording element, a recording position in a second direction is sequentially changed, and the first recording element and the second recording element are sequentially switched to form patterns of a second stage to N+1-th stage.SELECTED DRAWING: Figure 1
