A high-quality image conforming to the scanning speed of a recording head can be recorded through a simple arrangement in which 128 recording elements (segments) are divided up into eight blocks (each block comprising 16 segments). In order to perform recording by the initial block, a code of the corresponding three bits is supplied to a 3to8 decoder, whereupon a signal BE1 is outputted to made segments 1, 2, 17, 18, . . . , 113, 114 the object of drive. When a signal ODDENB attains a high level, segments 1, 17, . . . , 113 are driven and dots are formed at recording column positions by each segment. By subsequently sending a signal EVENENB to the high level, segments 2, 18, . . . , 114 are driven. Here the interval between the signals ODDENB and EVENENB is changed in conformity with the scanning speed of the recording head.
