摘要:
Aspects of the present invention provide an ink-jet recording method including the step of applying an ink to a recording medium by discharging the ink from a recording head by action of thermal energy and the step of fixing the ink to the recording medium by heating the ink applied to the recording medium. The ink contains water, a self-dispersing pigment, and resin particles. The resin particles have a glass transition temperature of not less than 25° C., an average particle diameter of 70 nm or more and 220 nm or less, and an acid value of 25 mg KOH/g or more and 150 mg KOH/g or less.

摘要:
An image forming process provides an excellent ink fixation effect for high speed, low energy consumption printing. Two-valued or multi-valued gradation expression of a picture element, or the smallest output unit, is realized by controlling the number of liquid droplets impacting on a recording medium for each dot formed on the recording medium. The liquid droplets are subjected to physical or chemical modification so as to be fixed to the recording medium. The present invention is also directed to an image forming apparatus, an ink for liquid droplet recording and a liquid droplet ejection and projection method that can use the image forming process.
