ABSTRACT:
A thermal recording device scans a laser beam over a thermosensitive recording medium which comprises a support coated with a coloring agent, a color developer, and a light absorbing dye and produces a color having a density commensurate with the lever of a thermal energy applied thereto, thereby to record an image thereon. The thermal recording device has a laser beam applying mechanism for emitting and applying a laser beam modulated by an image to be recorded to the thermosensitive recording medium, a temperature or humidity detecting mechanism for detecting a temperature or humidity with respect to the thermosensitive recording medium, and a controller for correcting the intensity of the laser beam emitted by the laser beam applying mechanism based on the humidity detected by the humidity detecting mechanism.
