Abstract: A rubber composition capable of manufacturing a sheet transport roller having an excellent friction coefficient and wear resistance. A sheet transport roller rubber composition contains an ethylene-?-olefin-diene copolymer as a base rubber, a sulfur-based crosslinking agent, and a coumarone-indene resin. It is preferable that the sheet transport roller rubber composition be obtained by mixing the base rubber and the coumarone-indene resin at a temperature equal to or higher than a softening point of the coumarone-indene resin to prepare a mixture, and then mixing this mixture with a sulfur-based crosslinking agent.

Abstract: In a tread-forming surface of a mold, a contour of a land surface-forming portion located between two projections among at least three land surface-forming portions can be represented by a single circular arc that is convex outward. In a case where, of the two projections, one projection is a wide projection and the other projection is a narrow projection, when a surface that has a contour represented by at least one circular arc and that is tangent to the at least three land surface-forming portions is defined as a reference surface of the tread-forming surface, a drop distance from the reference surface to an end on the wide projection side of the land surface-forming portion can be longer than a drop distance from the reference surface to an end on the narrow projection side of the land surface-forming portion.
