摘要: A printing method includes discharging ink to a substrate, heating a non-ink-discharged side of the substrate at T1, and heating an ink-discharged side of the substrate at T2, wherein the ink contains an organic solvent A (boiling point lower than 250 degrees C.), an organic solvent B (boiling point of 250 degrees C.), and a resin, where 0 degrees C. C≤T2−T1≤90 degrees C. is satisfied, the proportion (organic solvent A/ink) is 30 percent by mass or less, the proportion (organic solvent B/ink) is 1 to 3 percent by mass, the proportion (resin/ink) is 5 to 15 percent by mass, the ink has a viscosity of 8.0 to 11.0 mPa-s at 25 degrees C. and 5.5 to 11.0 mPa-s at 36 degrees C., and a 2.5 μL ink droplet discharged to the substrate shrinks to 0.1 μL within 10.0 seconds at 25 degrees C.

摘要: A toner including a crystalline polyester and an amorphous polyester is provided. When the binder resin is extracted from the toner with tetrahydrofuran to obtain an extracted solution, and the extracted solution is heated to remove the tetrahydrofuran and obtain a deposit, the deposit contains spherical domains of the crystalline polyester having an average particle diameter of 7.0 μm or less.

摘要: An image forming method is provided. The method includes the steps of (a) applying an ink to a recording medium to form an image and (b) applying a pressure to the recording medium to which the ink has been applied. The ink comprises water, an organic solvent, and a colorant. When the ink is formed into an ink film, a maximum value of logarithmic damping ratio of the ink film is 1.50 or less and a time elapsed until the logarithmic damping ratio reaches the maximum value is 3,800 seconds or less, when measured by a rigid-body pendulum test at 60° C.
