Abstract
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.
