Abstract
An image forming apparatus includes: a conveying unit that conveys a recording medium; a liquid droplet ejection head that ejects liquid droplets onto the recording medium; an emission unit that emits a detection beam and a reference beam, which is farther from a conveying surface of the conveying unit than the detection beam, along the conveying surface of the conveying unit, the emission unit being provided upstream of the liquid droplet ejection head in a conveying direction of the recording medium; a light receiving unit that receives the detection beam and the reference beam emitted from the emission unit; and a floating determination unit that determines whether the recording medium is floated, based upon a magnitude of a difference between an amount of light of the detection beam received by the light receiving unit and an amount of light of the reference beam received by the light receiving unit.
