Abstract
An image forming apparatus includes a feeding unit, a detection unit provided downstream of the feeding unit, a measurement unit that measures a measured time from the start of conveyance of a recording material to the detection of the recording material, and a determination unit that performs renewal determination for determining whether the feeding unit has been replaced with a new feeding unit. Thus, replacement of the feeding unit with a new feeding unit can automatically be detected.
