ABSTRACT:
A thermosensitive recording sheet is conveyed relative to a thermal head. To effect thermal recording, the thermal head applies heat energy to the recording sheet. The recording sheet is preheated with preheating energy shortly before recording of the recording sheet with the thermal head. The preheating energy is lower than enough to color the recording sheet, but heightens temperature of the recording sheet upon movement of the recording sheet to the thermal head. The heat energy to be applied by the thermal head is reduced according to the preheating energy.
