A transparent second layer having a heat insulating effect is provided between the first layer and the third layer, which becomes transparent when returned to room temperature after being heated to a temperature in the second range, and becomes opaque when returned to room temperature after being heated to a temperature in the second range. and a control means for controlling the conveying speed of the recording sheet or the amount of heat generated by the heat generating element in three operation modes, the control means controlling the conveyance speed of the recording sheet in the first operation mode or the heat generation amount of the heating element in the first operation mode. In a second operation mode, the first layer of the recording sheet is entirely brought to a temperature in the second range, and in a third operation mode, A heat-sensitive recording and reproducing device characterized in that the first layer is entirely heated to a temperature within the first range.
