Abstract
An image forming apparatus includes a conveyance unit, a detection unit, and a determination unit. The conveyance unit conveys a sheet. The detection unit detects a sound that emanates when the conveyance unit operates. The determination unit performs state determination. In a case where a volume of a sound detected by the detection unit is not higher than or equal to a predetermined sound volume, the determination unit determines that the conveyance unit is not normally operating. In a case where the detected sound volume is higher than or equal to the predetermined sound volume, the determination unit determines that the conveyance unit is normally operating.
