A highly reliable processing liquid for ink jet recording that even when used in printing on a plain paper, enables obtaining clear glossy images free from feathering and that even when left unused for a prolonged period of time, would not cause clogging of ink jet nozzle attributed to drying; an ink set comprising the same and an ink; a cartridge having these charged therein; a method of forming ink jet recording images therewith; and an image forming apparatus. In particular, a processing liquid for ink jet recording, comprising fine particles, which when brought into contact with a recording liquid comprising a coloring material and water, react with the coloring material, and at least one water-soluble organic solvent of 210ºC or higher boiling point, characterized in that the fine particles and the water-soluble organic solvent of 210ºC or higher boiling point are contained in proportion (a wt.%) and proportion (b wt.%), respectively, these proportions satisfying the relationships: 10 ≤ a < 40, and b/a > 1.50 wherein a and b are weight ratios (wt.%) based on the total weight of processing liquid. |
