Method for producing a fluororesin-coated roller or belt

A fluororesin coating layer fusion-bonded directly to a base member or to a rubber layer on a base member can be formed by conducting heating for a significantly short time. A fluororesin-coated roller or belt that has a fluororesin coating layer with few defects and a rubber layer underneath whose thermal deterioration is suppressed is provided. The production method therefor include a step of inserting a base member or a rubber-coated base member including a base member and at least a rubber layer on the outer peripheral surface of the base member into an empty space of a thermally shrinkable fluororesin tube; a preliminary shrinking step conducted according to need; a pressure fusion-bonding step of bringing the base member or rubber-coated base member into contact with a hot plate surface heated to a temperature in a range of 250° C. to 400° C. under pressure while rotating the base member or rubber-coated base member so as to fusion-bond the thermally shrinkable fluororesin tube onto the outer peripheral surface of the base member or the rubber-coated base member; and a reheating step and a rapid cooling step that are conducted according to need.
