Abstract
A failure diagnosis apparatus includes processing circuitry. The processing circuitry calculates a unique feature value from image data read from an image formed by an image forming apparatus, calculates a common feature value from the image data, and determines a failure part based on the unique feature value and the common feature value. The unique feature value is dependent on a model of the image forming apparatus. The common feature value is independent of the model of the image forming apparatus, and is common to a plurality of models of image forming apparatuses. The failure part is a component part that forms the image forming apparatus and has an abnormality.
