Abstract
An image forming system includes first and second generation units, a setting unit, and a prognosis unit. For a monitoring item whose detection values, being detected during an image forming operation in an image forming apparatus in which a trouble occurred within a predetermined time period after an operating condition was changed, were changed to an abnormal state, the first generation unit generates characteristic information indicating a variation state of the detection values. The setting unit sets criterion information to predict occurrence of a trouble, based on the generated characteristic information. The second generation unit generates, for the monitoring item corresponding to the set criterion information, characteristic information indicating a variation state of detection values in a target image forming apparatus. The prognosis unit predicts whether a trouble occurs after the operating condition is changed, based on a difference between the set criterion information and the characteristic information generated.
