Abstract
A thermal recording apparatus records image data line-by-line, using a thermal head having a linear array of heating elements. Each of the heating elements is shorter in the sub scan direction than in the main scan direction. To form an image of one recording line, the feeding of a recording paper and the transfer of ink onto the paper are repeated a plurality of times--for example, two times--using the image data for that line. The excellent thermal response of the heating element constructed as above, and the use of a plurality of recording operations for one recording line image formation, provides a uniform recording density distribution curve, so that the recorded image has high image quality and is substantially free from recording density irregularity. An additional recording control employed eliminates a nonimage part which will occur due to a varied recording speed.
