ABSTRACT:
A feeding device includes a feeding unit configured to be driven while being in contact with a recording sheet to feed the recording sheet, and a stacking unit configured to stack a plurality of the recording sheets and to press or release the stacked recording sheets to or from the feeding unit. Also, the feeding device includes a separating unit configured to separate the plurality of recording sheets fed by the feeding unit, one by one, a detecting unit configured to detect the recording sheet in an area downstream of the separating unit, and a control unit configured to control each of the units. The control unit switches a feeding operation between at least two feeding operations in accordance with a drive time of the feeding unit from when the feeding unit is started to be driven to when the detecting unit detects the recording sheet.
