摘要：
A first calculating unit calculates an allocation time required for forming a patch pattern. A second calculating unit calculates a maximum patch-pattern length of the patch pattern that can be formed within the allocation time based on the number of patch patterns that can be formed within the allocation time. A setting unit calculates a difference between an environmental temperature around the image forming apparatus and an environmental temperature at which the image forming condition stored in the storing unit is set, and newly sets an image forming condition for the patch patterns based on a result of comparing the difference with a predetermined threshold.
