A method and device for adjusting the alignment of a thermal print image forming apparatus for printing an image by applying heat to a medium using two thermal print heads is provided. The method includes printing first and second patterns by applying heat to the medium using the first and second thermal print heads simultaneously. The first and second patterns are sensed using a sensor, and the distance between the first and second thermal print heads is calculated by using the difference between the print positions of the sensed first and second patterns. The alignment between the print positions of the first and second thermal print heads is adjusted using the calculated distance. Accordingly, the distance between the two thermal print heads is accurately measured using the two simultaneously printed patterns, and the alignment of the image forming apparatus is conveniently and precisely adjusted using the measured distance between the thermal print heads. Thus, optimum print quality can be achieved.
