PURPOSE:To reduce noise and unnecessitate IR exposure device, by a method wherein a thermal head is brought into contact with a thermoplastic resin film of a thermal stencil paper, and is operated to generate heat, thereby perforating the film imagewise. CONSTITUTION:The thermal stencil paper comprises a thermoplastic resin film 1 and a porous base 2 adhered to each other, and a mount paper 4 is adhered to the base 2 by an adhesive layer 3. With the thermal head brought into contact with the film 1 of the stencil paper, electric currents are supplied to heating elements at parts corresponding to images to generate heat, whereby the film 1 is contracted at parts in contact with the head, resulting in that the film 1 is perforated imagewise. |
