Abstract

See full text

An image forming apparatus includes: a gear that transmits a drive force, which is supplied from a drive unit, to a photosensitive drum; a formation processing unit that, at arrival of each of specific formation timings, uses the photosensitive drum thereby to form a to-be-detected toner image that is based on a to-be-detected image having a specific density; an acquisition processing unit that acquires a variation width of a density in the to-be-detected toner image formed by the formation processing unit; and a determination processing unit that determines a failure timing of the gear based on the variation width for each of the formation timings.
