Abstract
An ink jet recording apparatus wherein ink drops can be controlled individually to assure high quality printing and adjustment in registration of ink nozzles in a drum circumferential direction can be performed at a sufficiently high resolution. The ink jet recording apparatus has a plurality of nozzles arranged such that drops of ink may impinge in an overlapping relationship at a location on a record medium supported on a rotary drum, and adjustment in registration of the nozzles in a drum circumferential direction is performed by a registration adjusting system by which such adjustment is performed using a registration adjusting clock signal having a frequency higher than a picture element recording signal. An optimum phase between disintegration of an ink jet and a recording pulse signal is determined in accordance with current values detected by a current detector connected to an electrically isolated conductive drop catcher.
