Fault diagnosis equipment, the fault diagnosis method, recording medium and image forming apparatus

摘要

PPROBLEM TO BE SOLVED: To provide a failure diagnosis device that performs failure diagnosis of a fixing section of an image forming device such as a copy machine, a printer and a facsimile, a failure diagnosis method, to provide an image forming device in which the failure is diagnosed by the failure diagnosis device or the failure diagnosis method, and to provide a computer-readable recording medium that stores a program for performing the failure diagnosis method. PSOLUTION: A failure diagnosis device uses: a first feature quantity computing means 113 that computes a first feature quantity representing an average of a plurality of driving loads recorded by a driving load recording means that records the driving load acquired by a driving load acquiring means that acquires the driving load of the fixing section of the image forming device 100; a second feature quantity computing means 113 that computes a second feature quantity representing a variance of the plurality of paper transport periods of time; and a diagnosis means 113 that performs failure diagnosis including estimation of a cause of a failure of the fixing section using the first feature quantity and the second feature quantity.
