Claim:
1. An image forming system comprising: an image output device to output an image on a recording medium with a mixture of a plurality of basic colors based on an image data array combining the basic colors; a measurement sensor to measure a reflection characteristic of at least a part of the image output by the image output device; tone correction value generation processing circuitry to generate, for each of the basic colors, a tone correction value for correcting a tone characteristic of the basic color by synthesizing a correction array forming a regular matrix based on the reflection characteristic measured by the measurement sensor and the image data array; and tone correction processing circuitry to correct an image output by the image output device with the tone correction value, wherein the tone correction value generation processing circuitry synthesizes the correction array based on change mode data serving as a basis for approximating a change in the tone characteristic of each of the basic colors.
