To increase the printing speed by distributing data processing of a printing head, an image recorder is provided with a print buffer for storing print data received from an information processor, a printing head having nozzles for plural channels that print on the basis of the print data stored in the print buffer, a 4-bit shift register unit that temporarily stores the print data of the print buffer and sequentially supplies the print data for each dot to the printing elements, and a buffer controller that divides the nozzles into odd and even channel groups and transfers the print data corresponding to the channel groups with a staggered timing to the 4-bit shift register unit from the print buffer.
