<p>PURPOSE: To provide a paper feed roller having durability, elasticity, and flexibility like rubber and also having moldability like resin, having a superior abrasion resistance, and having a sufficient carrying force relative to, especially, a silica sheet. CONSTITUTION: This paper feed roller 1 is formed by molding thermoplastic elastomer composition, in which crosslinkable rubber or thermoplastic elastomer is dispersed by dynamic crosslinking, in thermoplastic resin or the thermoplastic elastomer into a roller state. At least, the surface layer of the roller includes titanium oxide at the ratio of not less than 1.5% but not more than 50% in a volume percentage.</p> |
