Abstract

A thermal dot printer controls energy applied to individual heat generating members to control the amount of heat generated by the heat generating members, thereby controlling the ink melting area on an ink ribbon, and transfers the melted ink on a paper to print a gradation image on the paper. The size Lm of each heat generating element in the main scanning direction and the arranging pitch DOPm of the heat generating element in the main scanning direction have a relationship of Lm<=DOPm*(2/3), while the size Ls of each heat generating element in the sub scanning direction has a relationship of Lm<Ls<=DOPs with respect to the pitch DOPs in the sub scanning direction and the size Lm of the heat generating element in the main scanning direction.
