A control method of an injection molding machine is implemented so that a screw is rotated at a predetermined speed in the reverse direction to a rotational direction in a measuring process in the whole or partial stroke of an injection process in the case where an in-line screw type injection molding machine is controlled. With the control method, when the screw is moved forward in the injection process, apparent position of a ridge of the screw in a predetermined position of a heating cylinder becomes stationary.
