PROBLEM TO BE SOLVED: To provide an image forming apparatus and a program for estimating a change in humidity with high accuracy.SOLUTION: When toner consumption estimated by a first estimating unit 14 is smaller than toner consumption estimated by a second estimating unit 18, an output unit 20 outputs high humidity information. When the toner consumption estimated by the first estimating unit 14 is larger than the toner consumption estimated by the second estimating unit 18, the output unit 20 outputs low humidity information. |
