Claim 9:
10. An image forming method performed by an image forming apparatus, the method comprising:
predicting a maximum density of an image formed by the image forming apparatus based on a colorimetric value associated with particular environmental information among environmental information stored in a memory that stores the colorimetric value of a gradation correction chart that is output by the image forming apparatus and the environmental information each time of acquisition of the colorimetric value, the particular environment information being within a predetermined range with reference to current environmental information, when the image forming apparatus is to output the gradation correction chart;
adjusting the maximum density of the image formed by the image forming apparatus in a case that the predicted maximum density is lower than a target maximum density that is set in advance for input image data according to which the image forming apparatus performs an image output; and
correcting a gradation correction table based on the colorimetric value of the gradation correction chart that is output by the image forming apparatus and the target maximum density.
