摘要：A paper feeding apparatus includes a transfer roller that provides a transferforce of a first direction onto the upper surface of a recording medium; a retard rollerthat faces the transfer roller to form a transfer nip and provides a transfer force of a

second direction opposite to the first direction onto the lower surface of the recordingmedium; a driving unit that drives the retard roller; and a power delivery unit thatconnects the driving unit to the retard roller by using a magnetic force and provides amagnetic driving force that is smaller than the transfer force provided by the transferroller when one recording medium exists in the transfer nip and is larger than a frictionalforce between two or more recording media when the two or more recording media existin the transfer nip.
