Abstract
An image forming method includes the steps of: depositing an ink containing 10% or more and less than 30% of a water-soluble high-boiling-point organic solvent having an SP value of 28 or lower, onto a recording medium in accordance with an image signal, the ink having a viscosity of 10 cP or lower in a case where a temperature of the ink is 25° C.; removing water contained in the solvent of the ink on the recording medium, by a heating drying device; and heating and pressurizing the ink so as to fix the ink onto the recording medium.

An image forming method comprising the steps of:
- depositing an ink containing 10% or more and less than 30% of a water-soluble high-boiling-point organic solvent having an SP value of 28 or lower, onto a recording medium in accordance with an image signal, the ink having a viscosity of 10 cP or lower in a case where a temperature of the ink is 25° C.;
- removing water contained in the solvent of the ink on the recording medium, by a heating drying device;
- and
- heating and pressurizing the ink so as to fix the ink onto the recording medium.
An image forming method comprising the steps of:
- depositing an aggregating treatment liquid onto a recording medium;
- depositing an ink containing 10% or more and less than 30% of a water-soluble high-boiling-point organic solvent having an SP value of 28 or lower, onto the recording medium in accordance with an image signal, a viscosity of the water-soluble high-boiling-point organic solvent being 5 cP or lower in a case of a 30% aqueous solution at 25° C.;
- removing water contained in the solvent of the ink on the recording medium, by a heating drying device;
- and
- heating and pressurizing the ink so as to fix the ink onto the recording medium.
An image forming apparatus, comprising:
- an ink droplet ejection device which deposits an ink containing 10% or more and less than 30% of a water-soluble high-boiling-point organic solvent having an SP value of 28 or lower, onto a recording medium in accordance with an image signal, the ink having a viscosity of 10 cP or lower in a case where a temperature of the ink is 25° C.;
- a heating drying device which removes water contained in the solvent of the ink on the recording medium;
- and
- a heating and pressurizing fixing device which heats and pressurizes the ink so as to fix the ink onto the recording medium.
