Abstract

PURPOSE: To prevent change of fixation performance by specifying the structure of the elastic body surface layer of a roller.
CONSTITUTION: Silicone rubber layer 3 of heat fixing roller 1, silicone rubber layer 11 of pressure contact roller 6, and silicone rubber layer 11 of silicone oil coating roller 9 are impregnated with a silicone oil lower inviscosity than the silicone oil for coating in advance at normal temperature. Offset preventing fluid O in offset preventing fluid reservoir 12 is coated on silicone rubber layer via heat resistant cloth 14 and coating roller 10 to enhance offset preventing effect. At that time, since layer 3, in advance, was impregnated with the lower viscosity silicone oil, it is not impregnated with the higher viscosity silicone oil, when coated, permitting aging change of the diameter of layer 3 to be prevented, and wrinkles of a toner image support and change of fixation performance to be also prevented.
