<p>PURPOSE:To ensure high coefficient of friction by using silicone rubber containing a predetermined amount of phenyl radical in a siloxane unit as a material for a rubber roller for feeding, and whereby making it less possible to be affected by silicone oil. CONSTITUTION:The amount of phenyl radical contained in a siloxane unit of a silicone rubber composition is at least 3mol%. The silicone rubber composition is formed on the surface of a rubber roller for feeding. when the inside is formed into a multi-layer structure, for which an appropriate material that can be adhered to the silicone rubber composition is used, a layer consisting of the silicone rubber composition is formed into the thickness of no less than 0.5mm. Since the rubber roller for feeding thus manufactured has high coefficient of friction, and has excellent anti-silicone oil property, it can be used for an electronic copier carrying out paper feeding accurately, and even for double-side copying.</p> |
