Abstract
An ink jet recorder includes a plurality of recording elements which are arranged corresponding to each of a plurality of ejection outlets for ejecting ink in accordance with driving signals, a plurality of ejection passages corresponding to the ejection outlets and connected to a common chamber, a plurality of driving blocks formed by dividing the recording elements by predetermined number of units in the arrangement order, control elements for each of the driving blocks and for controlling the recording elements associated with each driving block in a simultaneous driving manner, a selection unit for selecting the driving block to be driven in order that at least adjacent driving blocks are not driven in sequence, and a supply unit for supplying driving signals to the driving block selected by the said selecting unit. With this arrangement, ink in ejection passages associated with a driving block adjacent the selected driving block will not be significantly affected when the selected driving block is driven.
