Abstract

PURPOSE: To eliminate the influence of variation in ink pressure and thereby obtain a high-quality image using a compact device by sequentially performing drive control of a plurality of drive circuits performing selective conduction of a plurality of electrothermal conversion elements based on a driving order setting data.
CONSTITUTION: A strobe terminal is provided for each drive IC 5 consisting of a 64-bit shift register 4, a 64-bit latch circuit 3, an AND circuit 2 and a transistor for thermal element drive. The thermal element 1 is driven in the divided drive mode through the drive transistor corresponding to only an AND circuit 2 to which a strobe signal entered from a drive sequential order control circuit 6 and an output from the 64-bit latch circuit 3 corresponding to each thermal element 1 are connected. The control circuit 6 interprets in which drive sequential order the thermal elements should be driven based on m-bit pattern data to be entered in drive sequential order setting data input terminals Do to Dm. Thus density irregularities can be eliminated without structural complication.
