The paper feeding device comprises: a cylindrical pick-up roller to pick up the paper loaded in a tray; a drive shaft rotatably supporting the pick-up roller and rotating in a predetermined direction; a solenoid for selectively rotating the drive shaft; and a power transmission member coupled to or spaced from the pick-up roller to selectively provide a driving force of the drive shaft to the pick-up roller. The power transmission member is engaged with the pick-up roller within a predetermined rotation range of the drive shaft.
