    Abstract: An inkjet printing apparatus includes a print head including an inkjet head having a nozzle surface; nozzles disposed on the nozzle surface, that spray an ink from the nozzles; and a heater that heats a temperature of the inkjet head to a reference temperature. The nozzles include a first nozzle having a first diameter; and a second nozzle having a second diameter different from the first diameter of the first nozzle, the nozzle surface includes a first area in which the first nozzle is disposed and a second area in which the second nozzle is disposed, the first area has a first temperature in case that the heater heats the inkjet head to the reference temperature, and the second area has a second temperature different from the first temperature in case that the heater heats the inkjet head to the reference temperature.
