To solve such problems that when an image can be formed by using a coated paper for commercial/publication printing with poor fixabilities as a recording medium and using a highly permeable recording liquid, the recording liquid is transferred on a spur for pressing the coated paper on which image formation is completed for discharging the paper, and that the missing of the image and a mark of the spur occur.

An image forming apparatus is equipped with a recording head 34 consisting of a liquid delivering head for delivering the highly permeable recording liquid to the coated paper for commercial/publication printing to form the image, a plurality of paper discharging rollers 62 for discharging the coated paper on which the image formation is completed, and the spurs 63 arranged in accordance with respective paper discharging rollers 62. A load applied on the coated paper by the spur 63 is set at a value of 0.07 N when a spring member 65 being a member for supporting the spur 63 is bent to 1 mm.
