Abstract:
Provided is a paper feeding roll that prevents paper transportation failures over a long time. A paper feeding roll 10 is provided with an axial body 12 and an elastic layer 14 formed on an outer periphery of the axial body 12. The circumferential surface of the elastic layer 14 has a plurality of projections 16 forming surface unevenness. Each projection 16 of the plurality of projections 16 is shaped such that a position X of a distal-end part preceding in an opposite direction to a paper feeding direction precedes, in the opposite direction to the paper feeding direction, a position Y of a base-end part preceding in the opposite direction to the paper feeding direction.
