装置の給紙装置。 A stopper for positioning the leading edge of the paper is provided on the downstream side of the loading plate in the paper feeding direction, and a driving means for switching between a first state of positioning the leading edge and a second state of releasing the positioning is connected to the stopper, and the stopper is in contact with each other. A roller for preventing double feeding for conveyance is disposed downstream of the stopper in the paper feeding direction, and an interlocking mechanism is provided for converting the state switching motion of the stopper into rotational motion and transmitting the rotational motion to the roller for preventing double feeding. A paper feeding device for an image forming apparatus, further comprising a one-way clutch interposed in the interlocking mechanism for allowing rotation of the double feeding prevention roller in the opposite paper feeding direction.
