Patent number: 9964907Abstract: 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.
