Elastic roller and fixing apparatus using same.

摘要

An elastic roller includes a conductive base (21); an elastic layer (22) on the conductive base (21); a surface parting layer (23) on the elastic layer (22), the surface parting layer (23) having a surface resistance of not less than 10<1><0> ohm; wherein the elastic layer (22) has a volume resistivity of not more than 10<7> ohm.cm. This structure avoids toner-offset and paper wrapping around the pressure roller (2) when fixing a tomer image to the sheet (5).
