Provided are an injection molding apparatus and an injection molding method for reinforcing fiber-containing resin material with which stable molding quality is obtained by preventing or limiting variations in the reinforcing fiber content. This injection molding apparatus is provided with: a heating cylinder (201); a screw (10) provided inside the heating cylinder (201) so as to be rotatable; a resin supply hopper (207) for supplying resin pellets (P); and a fiber supply device (213) provided in front of the resin supply hopper (207) for supplying reinforcing fiber into the heating cylinder (201). The screw (10) is provided with: a first stage (21) located in back for melting the resin pellets (P); and a second stage (22) located in front for mixing the melted resin pellets (P) with the reinforcing fibers (F). The lead (L2) of a second flight (28) provided in the second stage (22) is larger than the lead (L1) of a first flight (27) provided in the first stage (21).
