A thermal printer performs halftone reproduction of image by applying energy of an electrical signal which varies in response to the data representing tone graduation grade of the image into resistor heating element of the printer. The electrical signal to be applied to the heating element is not directly obtained from the above data but it is formed based on the conversion data stored in advance in a memory in which the characteristics of image receiving paper or inking material is taken into consideration.
