Paper feeding roll

Abstract

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 ( 20 b ) formed of foaming cells ( 16 ) being opened are provided to the outer circumferential surface ( 14 b ) of the elastic body layer ( 14 ).

What is claimed is: 
     
         1 . A paper feeding roll comprising:
 a shaft body; and   an elastic body layer formed on an outer circumference of the shaft body,   wherein the elastic body layer is a foamed body containing a hydrin rubber, and a cavity formed of foaming cells being connected with one another is provided inside the elastic body layer in a radial direction;   a first recess formed of the foaming cell being opened is provided in an inner circumferential surface of the elastic body layer;   a second recess formed of the foaming cell being opened is provided in an outer circumferential surface of the elastic body layer;   an average diameter of the foaming cells inside the elastic body layer in the radial direction is larger than an average diameter of the foaming cells on an outer side thereof in the radial direction; and   the hydrin rubber contains plant-based epichlorohydrin.
