摘要：
A recording member feeding device feeds a recording member such as a sheet in an image recording apparatus such as a copying machine. The recording member feeding device has a feeding rotary unit, a driving unit for driving the feeding rotary unit, and a driving power transmitting unit for transmitting he power of the driving unit to the feeding rotary unit. The recording member feeding device further has a rotation detecting unit for detecting the number of rotations of a rotary part in the rotary driving unit or in the driving power transmitting unit. The feeding rotary unit feeds the recording member by a length which is determined by the number of complete rotations detected by the rotation detecting units.
