Zusammenfassung:	Provided is a paper feeding roll that is capable of reducing conveying noise and suppressing adhesion of paper dust. A paper feeding roll (10) is provided with: a shaft body (12); and an elastic body layer (14) that is formed on the outer circumference of the shaft body (12), wherein the elastic body layer (14) is a foamed body that contains hydrin rubber, and has a cavity (18) formed of foaming cells (16) being connected with one another is located radially inward of the elastic body layer (14). The average diameter of the foaming cells (16) located inward of the elastic body layer (14) in the radial direction is larger than the average diameter of the foaming cells (16) located outward in the radial direction. Recesses (20b) formed of foaming cells (16) being opened are provided to the outer circumferential surface (14b) of the elastic body layer (14).
