An image density discrimination chart is used to discriminate a density of
a test image printed by an image forming apparatus. The chart includes an
exposing portion for exposing the test image when the chart is overlaid
relative to a printed recording material, a first comparison image having
an upper limit level of a latitude, permitted by the image forming
apparatus, for image density of the test image, and a second comparison
image having a lower limit level of a latitude, permitted by the image
forming apparatus, for image density of the test image.
