A method of forming an ink image with a thermo-sensitive ink by using a printing plate that is used in dry lithographic printing, and printing the ink image onto an object. An ink remover is placed via a thermo-sensitive ink layer that is in a heated state on a printing surface of a printing plate having a part receptive to ink and a part capable of repelling ink. The printing plate and the ink remover are separated after they are cooled so that the ink layer on the part capable of repelling ink is transferred to the ink remover. The ink image obtained on the printing plate or the ink remover is transferred to an object. Printing that does not require maintenance that has been essential to conventional dry lithographic printing becomes possible.
