摘要:
The present invention provides a sheet conveying roller, which effectively reduces the amount of paper dust accumulated on its outer peripheral surface to thereby suppress sheet transportation failure. The sheet conveying roller includes a nonporous tubular elastic member (1). The elastic member (1) has a plurality of recesses (6) or a plurality of through-holes (8) equidistantly arranged in a center axis (L1) direction thereof and equidistantly arranged in a circumferential direction thereof, and each having an opening having a round plan shape in an outer peripheral surface (2) thereof, wherein the recesses (6) each have a constant depth as measured thicknesswise of the elastic member (1), wherein the through-holes (8) each extend thicknesswise through the elastic member (1). A production method includes forming the elastic member by vulcanizing a rubber composition in a vulcanization mold having projections corresponding to the recesses or the through-holes.
