When the porous body comes into contact with the first image, first chemical species in the reaction liquid contributing to increasing the ink viscosity is contained, on the ink receiving medium and in the porous body, at a higher level in terms of molar equivalent per unit area than second chemical species in the ink also contributing to increasing the ink viscosity. In the liquid collection S5, the liquid is collected so that the liquid remains in the porous body on the side to be brought into contact with the first image.
