Abstract:
A feeding apparatus includes a feeding rotary member, a conveying rotary member pair, an output unit, a detection unit, and a control unit. The conveying rotary member pair includes first and second rotary members. The control unit stops a feeding operation when the detection unit does not detect the recording material by the time when a threshold time has elapsed after an operation of feeding a recording material is stated. The control unit determines that the recording material is stopped at a position on an upstream side relative to the nip portion in the feeding direction in a case where a rotation speed of the second rotary member, indicated by a state signal output from the output unit at least in a period of time from when the recording material reaches the nip portion to when the feeding operation is stopped, is faster than a threshold speed.
