There are provided an injection molding machine 10 having a screw 7 that can be moved in a cylinder 5, a pressure commanding device for generating a pressure command value applied to the screw 7, a pressure sensor 12 for sensing a pressure applied to the screw 7, a pressure subtracter 22 for calculating a deviation value between the pressure command value of the pressure commanding device and a sensed value of the pressure sensor 12, a pressure amplifier 201 for amplifying the deviation value of the pressure subtracter 22 at a predetermined amplification factor and changing an amplification factor value based on a pressure value of the pressure sensor 12, and a servo motor 14 driven based on an output value of the pressure amplifier 201 to move the screw 7.
