Abstract

PURPOSE:To enable to increase the quality of a printing without increasing a memory capacity in an ink jet recorder for correcting a distortion by the presence or absence of a deflecting droplet at the environment by using a specific correcting amount as the common correcting amount of a plurality of droplets. CONSTITUTION:Printing data are delayed by a shift register 15, and the output of O3 represents data to be charged. That is, O0, O1, O2 represent following charges, and O4-O7 represent preceding charged droplets. Accordingly, the preceding four droplets and the following three droplets are corrected. When the ink droplet is, for example, a heading droplet, the output of an NOR circuit becomes ''1'', the logical product of an AND circuit is enabled, the content of A0 is applied to a memory 12, and the preceding droplet is corrected. When there is the fifth preceding droplet, the O7 becomes ''1'', the NOR circuit becomes ''0'', the address A0 of the memory 12 becomes ''0'', the memory common to the fourth droplet is read and is corrected.
