To provide a liquid discharge device which can adequately correct a detection error of a position of a sheet material, and an image forming device.SOLUTION: A liquid discharge device includes a rotation member which holds a sheet material on a peripheral surface and conveys it, a liquid discharge part which discharges a liquid on the sheet material, a sheet material position detection part which detects a position of the sheet material, a first signal output part which outputs a first signal in response to a rotation amount of the rotation member, a second signal output part which outputs a second signal correlating with a moving amount of the sheet material on a peripheral surface of the rotation member, a correction data storage part which stores correction data obtained on the basis of the first signal and the second signal to correct the second signal, and a discharge timing generation part which generates a discharge timing of the liquid discharge part on the basis of the second signal and the correction data.SELECTED DRAWING: Figure 7 【課題】シート材の位置の検出誤差を適切に補正することができる液体吐出装置、及び画像形成装置を提供する。【解決手段】シート材を周面に担持して搬送する回転部材と、シート材に液体を吐出する液体吐出部と、シート材の位置を検知するシート材位置検知部と、回転部材の回転量に応じた第１信号を出力する第１信号出力部と、回転部材の周面におけるシート材の移動量に相関する第２信号を出力する第２信号出力部と、第１信号と、第２信号と、に基づいて取得された第２信号を補正する補正データを格納する補正データ格納部と、第２信号と、補正データと、に基づき、液体吐出部の吐出タイミングを生成する吐出タイミング生成部と、を有する。【選択図】図７
