Abstract
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.
