In a rotation transfer device, a paper feeding apparatus and an image forming apparatus, transfer projections are disposed on coupling members provided on the ends of a driving shaft and a driven shaft, so that the movement of one transfer projection in the peripheral direction can be constrained by the other transfer projection and a positioning member. Thus, rotation irregularity caused by reverse rotation torque applied by a function from the side of paper can be prevented.

[ What is claimed is:] [1.] A rotation transfer device, comprising:a driving shaft;a driven shaft;coupling members respectively provided on ends of the driving shaft and the driven shaft, through which the driven shaft and the driving shaft are removably coupled with each other;transfer projections respectively projected from opposing faces of the coupling members on a common circle away from axial centers of the coupling members, which are brought to a contact with each other for rotation transfer;a positioning member provided on one of the coupling members movably toward and away from the opposing face of the other coupling member, which is moved in a projecting direction to constrain movement of the transfer projection on the opposing coupling member in a direction away from the transfer projection on the coupling member having the positioning member, and is moved in a recessing direction to allow movement of the transfer projection of the opposing coupling member in a direction toward the transfer projection on the coupling member having the positioning member; andforce applying means for applying a force to the positioning member in the projecting direction.
