| Zusammenfassung: | To provide a highly durable paper feed roll that is less likely to cause paper feed defect due to accumulation of paper dust even after long-term use.SOLUTION: A paper feed roll includes a shaft body and an elastic body layer 3 formed on an outer periphery of the shaft body. A peripheral surface 31 of the elastic body layer 3 is provided with irregularity by a convex part 4. The convex part 4 integrally has a first convex structure 5 projecting from the peripheral surface 31 of the elastic body layer 3 and a second convex structure 6 projecting from a surface 51 of the first convex structure 5 in a needle shape.SELECTED DRAWING: Figure 2
【課題】長期間使用しても、紙粉の蓄積による用紙の搬送不良が起こりにくく、耐久性に優れた紙送りロールを提供する。【解決手段】軸体と、軸体の外周に形成された弾性体層３と、を備え、弾性体層３の周面３１には、凸部４により凹凸が設けられており、凸部４は、弾性体層３の周面３１から突出した第一凸構造５と、第一凸構造５の表面５１から針状に突出した第二凸構造６と、を一体に有する、紙送りロールとする。【選択図】図２ |
