Abstract
An image forming apparatus includes a feeding unit, a regulation member, a detection unit, and a control unit. The feeding unit feeds a recording material from a storage unit to a conveying path. In the storage unit, the regulation member controls a trailing edge of the recording material in a feeding direction. The detection unit detects time until the recording material reaches a predetermined position along the conveying path after the feeding unit begins to feed the recording material. The control unit determines a state of the regulation member based on the detected time. Where the time detected by the detection unit is a value between a first threshold and a second threshold, which is larger than the first threshold, the control unit determines that the regulation member is shifting from a position corresponding to a size of the recording material in the feeding direction.
