Abstract:
A thermal recording apparatus for two-dimensionally recording an image on a thermal recording material, said apparatus comprising:a thermal head comprising a plurality of heating elements arranged in a main direction, wherein said thermal head has a recording density of 400 dpi or more; and a transport means operable to impart relative movement between the thermal recording material and the thermal head in a sub-direction perpendicular to said main direction of the heating elements; wherein said thermal head records images by dividing heat recording into a plurality of heating points of a pixel using between 2 heating points and heating points per pixel in said sub-direction, wherein an on time of a control signal, which controls an ON-OFF cycle of said plurality of heating elements, is between 25% and 50% of a total time for the ON-OFF cycle of the control signal, said on time being based on a maximum density recording by the thermal head.
