Abstract
An image forming method is provided. The method includes the steps of: applying a liquid composition, comprising a pigment, water, a resin, and an organic solvent, to a recording medium having water-absorptivity to form an image thereon; and winding up the recording medium in a roll form after the applying, wherein the following formulae are satisfied: 1.00×10−3≤A≤4.00×10−1 0.010≤B/A≤0.100 where B (mg/cm2) represents an amount of the organic solvent contained in the image after the winding and A (mg/cm2) represents a total amount of the organic solvent contained in the image and the recording medium after the winding.

An image forming method comprising:
- applying a liquid composition, comprising a pigment, water, a resin, and an organic solvent, to a recording medium having water-absorptivity to form an image thereon;
- and
- winding up the recording medium in a roll form after the applying,
- wherein the following formulae are satisfied:
- 1.00×10−3≤A≤4.00×10−1
- 0.010≤B/A≤0.100
- where B (mg/cm2) represents an amount of the organic solvent contained in the image after the winding and A (mg/cm2) represents a total amount of the organic solvent contained in the image and the recording medium after the winding.
An image forming method comprising:
- (a) applying a liquid composition, comprising a pigment, water, a resin, and an organic solvent, to a recording medium having water-absorptivity to form an image thereon;
- and
- (b) applying a pressure of from 1.00×10−3 to 1.00×10 kgf/cm2 to the recording medium after the step (a),
- wherein the following formulae are satisfied:
- 1.00×10−3≤A≤4.00×10−1
- 0.010≤B/A≤0.100
- where B (mg/cm2) represents an amount of the organic solvent contained in the image after the step (b) and A (mg/cm2) represents a total amount of the organic solvent contained in the image and the recording medium after the step (b).
An image forming apparatus comprising:
- a storage storing a liquid composition comprising a pigment, water, a resin, and an organic solvent;
- a recording medium storage storing a recording medium having water-absorptivity;
- an applying device configured to apply the liquid composition to the recording medium to form an image thereon;
- and
- a winder configured to wind up the recording medium having the image thereon,
- wherein the following formulae are satisfied:
- 1.00×10−3≤A≤4.00×10−1
- 0.010≤B/A≤0.100
- where B (mg/cm2) represents an amount of the organic solvent contained in the image on the recording medium wound up by the winder and A (mg/cm2) represents a total amount of the organic solvent contained in the image and the recording medium wound up by the winder.
