Paper feed roller and method for producing paper feed roller

Abstract

The invention provides 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. 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.

Description

technical field [0001] The present invention relates to a paper feeding roller and a method for manufacturing the paper feeding roller. Specifically, the present invention relates to a method that not only has good softness and formability, but also improves the conveying force of conveyed materials such as paper. In particular, it can Paper feed roller that effectively prevents non-feeding of silicon paper. Background technique [0002] Rubber rollers are used in paper feeding mechanisms of inkjet printers, laser printers, electrostatic copiers, plain paper facsimile machines, automatic teller machines (ATMs) and the like. Since such rubber rollers must pick up conveyed materials such as paper and film materials, separate them, and send them out, excellent flexibility and high wear resistance are required as their characteristics. [0003] Also, this paper feeding roller is required to pick up, separate and convey various printing media such as gene...
