An injection molding machine includes a storage unit in which input information input via an operation unit and a molding condition under which molding is performed using a gain specified by the input information are stored in association with each other, and a control unit configured to generate a signal with a feedback-control, which uses a difference between a set value used to control an object to be controlled and an actual value measured from the object to be controlled and the gain specified by the input information associated with the molding condition, and to control a drive source using the signal to perform the molding, in a case where the molding indicated by the molding condition is performed.
