In a stamping device, a stamping stencil is produced and used which does not require manual application of ink to the stencil. Data concerning an image, which may include character, figure and/or symbol data, is input by a input unit, a thermal head generates heat on the basis of the data and transmits the heat to the thermal stencil paper disposed at the printing position. As a result, a corresponding pattern of pores is produced, by the heat of the thermal head, in the thermal stencil paper. Ink is supplied to the pores by an ink supply unit at an ink supplying position when pressure is applied to the back of the ink supply.
