ABSTRACT:
The image forming apparatus comprises: an ink application device which applies ink to a recording medium; a treatment liquid application device which applies treatment liquid which causes the ink to increase in viscosity or solidify, by reacting with the ink; an image processing device which generates image data of multiple values from an input image; a block dividing device which divides an image region to be formed on the recording medium according to the image data into a plurality of blocks; an evaluation value calculation device which calculates an evaluation value for each of the blocks for judging an application of the treatment liquid to each of the blocks, according to the image data; and a treatment liquid application control device which controls a mode of applying the treatment liquid to each of the blocks, by comparing the evaluation value with a previously established threshold value.
