The present invention provides an image forming apparatus including: a print head, including nozzle heads, configured to discharge ink droplets upward and movable between an image forming area in which images are formed on a recording medium and an idle discharge area in which idle discharge of the ink droplets is performed to clean the nozzles; an endless belt ink receiving member, disposed above the print head in the idle discharge area in which the print head performs idle discharge and configured to hold the idly-discharged ink; an ink receiving member driver operatively connected to the ink receiving member to circularly drive the ink receiving member; and a cleaner disposed downstream of the idle discharge area in the direction of rotation of the ink receiving member and configured to remove the ink from the ink receiving member.
