Abstract
A roll-sheet feeding device having a roll sheet wound in a roll to feed a portion of the roll sheet to an image forming unit, includes a progressive mechanism to transmit a drive force from a drive source to transfer the portion of the roll sheet from the roll in a progressive direction, a roll-sheet drive mechanism to receive the drive force transmitted via the portion of the roll sheet transferred in the progressive direction, a rewinding mechanism to transfer the portion of the roll sheet in a direction opposite to the progressive direction via the roll-sheet drive mechanism to rewind the roll sheet, and a regenerating mechanism to obtain the drive force from the roll-sheet drive mechanism and transmit the obtained drive force to the progressive mechanism to regenerate the transmitted drive force as another drive force in addition to the drive force from the drive source.
