Zusammenfassung:Provided is a paper feeding roller in which recesses due to deformation are unlikely to be formed even when contact with another roller in one location continues for a comparatively long period of time, particularly as a conveying roller or the like. A paper feeding roller that has a shaft measuring 6 mm in exterior diameter pressure-welded to the outer circumferential surface under a load of 600 g in a high-temperature environment of 60° C. for 24 hours is left at room temperature for eight hours while being pressure-welded, after which the recess amount obtained using the difference (T)0−T1, between the thickness T1 (mm) of the position where the shaft was pressure-welded and the thickness T0 (mm) of a position where the shaft was not pressure-welded, is 0.1 mm or less.
