A method for forming a resin molded article includes a step of extruding a thermoplastic resin intermittently at a predetermined speed from an extrusion slit, such that the resin droops downward in a shape of a sheet. The method further includes the steps of: feeding the extruded sheet-shaped resin downward by a pair of rollers; and forming the sheet-shaped resin with a mold. In the step of feeding the sheet-shaped resin, one of the rollers is pressed against the other, but not to the extent of crushing the sheet-shaped resin, regardless of the thickness of the sheet-shaped resin. In addition, a surface temperature of each of the rollers is set lower than a temperature of the sheet-shaped resin and within a predetermined temperature range. This method can prevent sliding contact between the rollers and the sheet, while preventing the sheet from being wound around the rollers.
