A thermal activator has a heating device that heats a heat sensitive adhesive layer of a heat sensitive adhesive sheet to activate the adhesive layer. The adhesive sheet has a printable surface formed on one side of a sheet-like base and the heat sensitive adhesive layer formed on the other side thereof. A transporting device transports the heat sensitive adhesive sheet in a predetermined direction. A sheet material prevents a heat sensitive adhesive of the heat sensitive adhesive layer or a denatured product of the heat sensitive adhesive from adhering to the transporting device.

The heat-sensitive self-adhesive sheet has a sheet-like substrate having a printable surface on a first side thereof and the heat-sensitive adhesive layer on a second side thereof. An energy control device controls the thermal head by applying one or more voltage pulses to the heat generating elements for energizing the heat generating elements to thereby thermally activate an area of the heat-sensitive self-adhesive layer in one step. When a series of the voltage pulses are applied to the heat generating elements, the energy control device selectively switches between the heat generating elements to be energized by the voltage pulses each time one of the voltage pulses is applied.
