A recorder using a line thermal head is provided with a digital delay circuit for driving heating elements a plurality of times on the basis of one piece of recording data and a thermal history circuit for controlling the driving of the heating elements on the basis of accumulated heat temperature data of the heating elements themselves stored in advance in a memory. This arrangement makes it possible to reduce stepped recording attributable to high speed feeding of recording paper, and to prevent the lowering of printing quality caused by the continuous driving of the heating elements.
