An image forming apparatus includes an ink having a dynamic surface tension of from 30 to 50 mN/m at a life time of 15 msec at 25 degrees C., a container containing the ink, and a head configured to discharge the ink to a fabric including a first fabric containing synthetic fiber in an amount of more than 50 percent by mass and a second fabric containing natural fiber in an amount of 50 percent by mass or greater, wherein the droplet of the ink discharged to the first fabric is larger than the droplet of the ink discharged to the second fabric.
