    • An image forming apparatus includes: conveying means for conveying a recording medium; a liquid droplet ejection head configured to eject liquid droplets onto the recording medium; emission means (230) for emitting a detection beam (L1), which is used for detecting the recording medium, and a reference beam (L2), which is farther from a conveying surface of the conveying means than the detection beam (L1), along the conveying surface of the conveying means, the emission means being provided upstream of the liquid droplet ejection head in a conveying direction of the recording medium; light receiving means (240) for receiving the detection beam and the reference beam; and floating determination means (260) for determining whether the recording medium is floated, based upon a magnitude of a difference between an amount of light of the detection beam (L1) received by the light receiving means and an amount of light of the reference beam (L2)received by the light receiving means.
    • 一种图像形成设备包括:传送装置,用于传送记录介质; 液滴喷射头,其被构造成将液滴喷射到所述记录介质上; 用于发射用于检测记录介质的检测光束(L1)和比检测光束(L1)更远离传送装置的传送表面的参考光束(L2)的发射装置(230) 沿着所述输送装置的输送表面,所述发射装置在所述记录介质的输送方向上设置在所述液滴喷射头的上游; 光接收装置(240),用于接收检测光束和参考光束; 和浮动确定装置(260),用于基于由光接收装置接收的检测光束(L1)的光量与参考光束的光量之间的差值的大小来确定记录介质是否浮动 (L2)由光接收装置接收。
