Abstract
To provide a fixing pressure roller production method which can readily provide a fixing pressure roller in which no abnormal foaming occurs at the interface between the elastic layer and the metallic core. The method of the present invention includes a molding step of molding, under reduced pressure, an unvulcanized silicone rubber containing a chemical foaming agent; after the molding step, a leaving step of allowing the molded product to stand for a predetermined period of time; and after the leaving step, a foam-curing step of vulcanizing the unvulcanized silicone rubber, to thereby yield an elastic layer formed of a foamed silicone rubber.
