Provided is a technique for manufacturing a toner supply roller in which the toner conveying performance and the scraping performance of unneeded toner are excellent as well as the above-mentioned problems in molding can be resolved. Also provided is a method for manufacturing a toner supply roller including: an insertion process in which a roller membercomprising a shaftand an elastic layercomposed of a foam having a columnar shape supported on the outer periphery of the shaft is inserted into a cylindrical forming tool m having on the inner peripheral surface irregular concaves and convexes or a recessed groove along the longitudinal direction; a transfer process in which the roller member inserted into the cylindrical forming tool is heated and the irregular concaves and convexes or the recessed groove along the longitudinal direction on the inner peripheral surface of the cylindrical forming tool are transferred on the surface of the roller member; and a releasing process in which the roller member on the surface of which the irregular concaves and convexes or the recessed groove along the longitudinal direction are transferred is taken out from the cylindrical forming tool to obtain a roller.
