Abstract
A method for producing a fixing-unit member including a base, a rubber elastic layer, and a PFA layer includes a step of forming a primer layer by applying a primer containing a low-melting fluorocarbon resin to the outer circumferential surface of a rubber roller having the rubber elastic layer on the outer circumferential surface of the base; a step of sheathing the rubber roller with a thermally shrinkable tube formed by diametrically expanding a PFA tube so as to have an inner diameter more than the outer diameter of the rubber roller; a step of forming the PFA layer from the thermally shrinkable tube by heating the thermally shrinkable tube so as to be thermally shrunken and fused with the rubber roller; and a reheating step of heating the PFA layer to a temperature equal to or higher than the melting point of the PFA contained in the PFA layer.
