Abstract

PURPOSE:To make uniform the quality of record at the time of continuous recording by application of a power for coloration while keeping the temperature of heating portion and its adjacent area constant by applying a low-level voltage thereto as the first step. CONSTITUTION:The shaded portion, as shown in Fig., is heated by application of a power pulse of a low level not to give dot color even when applying it to the heating portion in order to heat the heating portion at a certain level. Then, on the basis of an image signal for forming letters and image, a power pulse of a constant value and high level is applied to the heating portion to obtain dot color. At the time of high-speed recording by thermal head, the life of the heating element can thus be more lengthened than in the case where the abrupt heating of the heating element is repeatedly conducted.
