Abstract
An image forming apparatus that is capable of specifying a causal part of an error on the basis of an occurred phenomenon even for a low-skill operator. Causal part candidates are candidates of parts of the apparatus that can cause an error in the apparatus. An associated component is relevant to one of the causal part candidates and a state change thereof is detectable. A detector detects the state change of the associated component. A memory stores the state change of the associated component detected by the detector in association with detected time. A processor executes a function for detecting the error and a function for specifying an error causing part that is the part causing the error from among the causal part candidates based on time at which the error is detected and information stored in the memory.
