PURPOSE:To equalize recording density by each heating dot for various heating patterns for obtaining good recorded pictures by adjusting the heating current of each heating dot according to the number of adjacent heating dots. CONSTITUTION:On a recording head 1, heating dots h1, h2,..., made of resiters, are arranged in a row and each heating dot h1 is selectively heated and driven by driving transistors T0, T1,... for selective control according to the output of each stage in a shift register 2 and also a transistor 3 for common control. In this case, current-regulating circuits C0, C1... are provided for each heating head and the collector current values of the transistors T0, T1,... are adjusted according to the selection number for heating of the adjacent heating dots. Thus, the recording density by each heating dot h1 can be equalized. |
