Abstract
An apparatus, system, and method of predicting failure of a fixing device of an image forming apparatus are provided. Based on a plurality of sheet transfer time values of the fixing device, a first characteristic value that is an average value of the plurality of sheet transfer time values, and at least one of a second characteristics value that indicates the variance of the plurality of sheet transfer time values and a third characteristics value that indicates the maximum value of the plurality of sheet transfer time values are calculated. Using a determination result generated based on the first characteristics value and the at least one of the second and third characteristics values, failure of the fixing device is predicted.
