Abstract
A test chart is obtained by printing a test chart image using an image forming apparatus for skew measurement of the image forming apparatus. The test chart includes a first scale image that includes a scale along a secondary scanning direction and a second scale image that includes a scale along the secondary scanning direction. The first and second scale images are arranged along a primary scanning direction. When a top-end part of the test chart is folded back, a top end of the test chart indicates different values from each other on the first and second scale images in accordance with a skew angle.
