Abstract
The present invention provides an electrostatic attracting-type ink jet recording method by which an ink dot which has adhered to the recording medium or intermediate recording material can be prevented from affecting the drawing direction of the subsequently jetting ink, whereby an ink can be invariably allowed to jet onto a proper position to form an image with a high quality. An electrostatic attracting-type ink jet recording method is provided which comprises applying a voltage pulse across a recording electrode connected to a recording head and an opposing electrode disposed on the opposite side of a recording medium or intermediate recording material, whereby the resulting Coulomb's force causes an ink to jet onto said recording medium or intermediate recording material through an orifice in the recording head to form an image thereon, characterized in that the relaxation time of the ink calculated by multiplying the dielectric constant of the ink by the volume resistivity of the ink during the operation of ink jet recording is in the range of 0.01 to 2 times the ink jetting period.
