A processing liquid containing an insolubilizer of polymer as the insolubilizer is thinned out at a relatively low printing ratio, i.e., at a given ratio relative to dots of a black ink and applied after the Bk ink is applied. Thereby, a reacting product is fixed in a part relatively shallow and close to the surface of a printing medium without diffusing deep into the medium and thus can increase optical density of a printed phi image. In this case, the fixation can be accelerated when the processing liquid is highly penetrative.
