    Abstract: In order to produce a heat-sensitive record material having high speed recordability without fogging a heat-sensitive record material having a heat-sensitive record layer coated thereon is passed through a nip between a metal roll and an elastic roll of 42.degree. to 69.degree. Shore-D hardness defined by ASTM Standard, D-2240 at a nip pressure enough to obtain a Bekk smoothness of 150 seconds or above on the record layer surface.
