<p>PURPOSE: An injection molding machine is provided to control to desired temperature of the zone in which a band heater does not exist and to flexibly controlling temperature of a heating cylinder. CONSTITUTION: An injection molding machine comprises a heating cylinder(1), a heating unit, and a temperature control unit(20). The heating cylinder is divided to a plurality of temperature control zones(Z1-Z4) and controls the temperature. The heating unit heats the predetermined temperature control zone among the plurality of temperature control zones. The heating unit is a band heater(3) heating the heating cylinder. The temperature control unit controls the temperature of place except the predetermined temperature control zone to the heating unit to the prescribed temperature based on detected value of a temperature detection unit which is installed in the place except the predetermined temperature control zone.
