An image forming apparatus according to the present invention comprises medium-conveyance means having a conveyance surface that moves at a speed V, and a plurality of liquid ejecting heads disposed in a movement direction of the surface. Associated with the maximum value of variations of a height of the surface with respect to a conveyance reference surface, the maximum error amount of a thickness of a print medium and the maximum amount of relief from the conveyance surface, the maximum height HCX of a cockling produced on the medium, and a cockling height after passage of a predetermined time L/V since a liquid is firstly ejected to the medium by the upstream liquid ejecting head a gap between an ejection opening surface of the head located on the downstream side and the conveyance surface is set, and a distance L between the upstream and downstream liquid ejecting heads is set shorter than (V/VCX)HCX. |
