摘要： An image forming apparatus includes a failure prediction unit, an image identification unit, a simulated-image generating unit, and an output unit. The failure prediction unit prepares an index value indicating a condition of the image forming apparatus based on multidimensional signal, obtained by monitoring the image forming apparatus, and compares the index value with a first threshold value to predict a failure mode of the image forming apparatus. The image identification unit identifies types of abnormal images based on the failure mode predicted by the failure prediction unit. An identified abnormal image is predicted to be appear a given time later. The simulated-image generating unit generates a simulated image of the identified abnormal image. The output unit outputs the identified abnormal image as the simulated image.
