    • An image forming apparatus comprising: a conveying unit; a liquid droplet jetting head that jets liquid droplets onto a recording medium conveyed by the conveying unit; an uplift amount detection unit that is provided at the recording medium conveying direction upstream side of the liquid droplet jetting head, projects and receives light along the conveying unit, and detects an uplift amount of the recording medium; a control unit that lowers the conveying speed of the conveying unit or separates the liquid droplet jetting head from the conveying unit when the uplift amount detected is a threshold value or greater; a temperature detection unit that detects temperatures; and a correcting unit that corrects the threshold value or the uplift amount based on the temperature difference between a temperature detected at the periphery of the uplift amount detection unit and a temperature detected at the periphery of the liquid droplet jetting heads.
    • 一种图像形成装置,包括:输送单元; 液滴喷射头,其将液滴喷射到由输送单元输送的记录介质上; 提升量检测单元,设置在所述液体喷射头的记录介质输送方向上游侧,沿着所述输送单元突出并接收光,并检测所述记录介质的隆起量; 当检测到的隆起量为阈值或更大时,控制单元降低输送单元的输送速度或将液滴喷射头与输送单元分离; 检测温度的温度检测单元; 以及校正单元,其基于在隆起量检测单元的周边检测到的温度与在液滴喷射头的周边检测到的温度之间的温度差校正阈值或隆起量。
