A method for forming a lubricating layer, comprising the steps of a process for inserting a bearing, which has a tubular-shaped retainer holding a plurality of rollers and inserted in an outer ring, in a forming die having an inner diameter greater than an outer diameter of the outer ring of the bearing; a process for feeding a fluid lubricant including a thermoplastic resin into the forming die; a process for reducing pressure in the forming die with the fluid lubricant fed therein to remove air bubbles included in the fluid lubricant; a process for pressing a cylindrical elastic solid, which has an outer shape greater than a minimum inner diameter of the retainer, into an inscribed circle in which the plurality of rollers are inscribed; and a process for heating and setting the thermoplastic resin to form a lubricating layer.
