Patent ID: 8182079

Claim:
An image forming method, comprising the steps of: depositing an aggregating treatment liquid containing an aggregating agent onto a recording medium, the aggregating agent containing 10% or more and 90% or less of a water-soluble high-boiling-point organic solvent having a Solubility Parameter (SP) value of 30 or lower (MPa) 1/2 measured at 25° C. and being configured to aggregate a latex and/or a pigment; starting drying of the aggregating treatment liquid deposited on the recording medium within five seconds after the step of depositing the aggregating treatment liquid onto the recording medium; ejecting an ink containing 10% or more and 90% or less of a water-soluble high-boiling-point organic solvent having a Solubility Parameter (SP) value of 30 or lower (MPa) 1/2 measured at 25° C. and the latex and/or the pigment in accordance with an image signal, so as to be superimposed on the aggregating treatment liquid deposited on the recording medium; and removing water contained in the solvent of the ink on the recording medium in such a manner that the water contained in the ink becomes 4 g/m 2 or less when converted to a deposition volume.
