(57) A thermal head which comprises a plurality of heating resistor strips (14, 16) arranged
in a main scanning direction on an insulator layer (10). Each heating resistor strip
(14, 16) includes a plurality of resistor pieces (261, 262,..., 281, 282, ...) aligned
in a main scanning direction. The resistor piece (281. 262,..., 281, 282,...) of each
heating resistor strip (14, 16) is displaced in a main scanning direction so as not
to be superposed in the subscanning direction. The resistor pieces (261, 262,...,
281, 282, ...) of each heating resistor strip (14, 16) are supplied with currents
in response to bit data at a predetermined timing and are thus heated to obtain a
line of recording dots for a main scanning line.
