ABSTRACT:
A thermal printer for forming an image on a sheet, with the image having a plurality of line image data. The thermal printer includes a thermal head having a plurality of linearly arranged thermal elements for forming the image. The total number of the thermal elements to be driven is determined. The thermal elements are driven for a predetermined time period in accordance with the line image data if the number of thermal elements to be driven is not greater than a predetermined value. If the total number of the thermal elements to be driven is greater than the predetermined value, then the predetermined time period is divided into a number of fractional time periods and the thermal elements are intermittently driven for each of the fractional time periods. The predetermined value is determined to avoid sticking between the thermal head and a thermosensitive sheet due to excess heat.
