Abstract
An ink jet recording apparatus is provided with a conveying unit, a drive roller controller and a discharge timing controller. The drive roller controller controls a rotation speed of a drive roller based on pulse signals output by an encoder and corresponding to an angular velocity of a driven roller and an actual outer diameter of the driven roller. The discharge timing controller controls an ink discharge timing based on signals obtained by attenuating multiple frequency components of a target frequency corresponding to a pulse number of the pulse signals output from the encoder during one turn of the driven roller in the pulse signals and an actual outer diameter of the driven roller.
