Abstract: A method for manufacturing a thermal transfer image-receiving sheet support that can be used to obtain a thermal transfer image-receiving sheet that maintains its gloss and that has excellent handleability and high condition uniformity while preventing the formation of air bubbles in an adhesive layer. A resin is supplied to one side of a substrate, which is passed between a cooling roller A and a rubber roller A. A porous film is stacked on another side of the substrate through a resin, and the substrate is passed between a cooling roller B and a rubber roller B. The cooling rollers A and B have surfaces with a ten-point average roughness (Rz) of 5 to 30 μm and 0 to 20 μm, respectively. The rubber rollers A and B have a rubber hardness (durometer (Type A)) of 60 to 95 and 50 to 80, respectively.
