ABSTRACT:
A thermal master making device and a thermal recording device each including a thermal head and a platen roller. The master making device thermally perforates, or cuts, a thermosensitive stencil for making a master while the recording device thermally records an image on a thermosensitive recording medium. The devices each reduce the corrosion of an expensive thermal head in any environmental conditions while guaranteeing the conveyance of the stencil or the recording medium. The stencil and recording medium each contain a corrosive substance in an antistatic agent or adhesive or an overcoat layer thereof. The corrosion of the head would directly translate into defective images. With the above devices, it is possible to reduce a burden on the user and to extend the life of the head. Extending the life of the head is desirable from the environmental standpoint also.
