Process for forming image with liquid droplets, image forming apparatus utilizing such process and process for ejecting and projecting liquid droplets

摘要

This invention provides an image forming process that by turn 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 also provides an image forming apparatus, an ink for liquid droplet recording and a liquid droplet ejection and projection method that can be used for the image forming process.
