Abstract:
An ink jet recording method for recording an image on a recording medium by using an ink jet recording head, comprising the step of performing an image recording by setting time T (ms) required for an ink droplet ejected onto a recording medium to be absorbed completely by the recording medium, a maximum amount V (ml) of the ink droplet ejected from the recording head in a single operation, an average diameter D (m) of an equivalent circular area of the dot when the ink droplet impinges on the recording medium, and an ink absorption coefficient Ka (ml/m.sup.2.multidot.ms.sup.1/2) of the recording medium obtained by the Bristol method, said T, V, D and Ka having the relationship ""T=(4V/.pi.D.sup.2 Ka).sup.2 "", to meet the condition of T.ltoreq.Tx (ms), Tx representing the time between a step for a first ink droplet to impinge on a certain position of the recording medium and another step for a second ink droplet to impinge on the same position of the recording medium.
