PROBLEM TO BE SOLVED: To detect a discharge failure of a nozzle without consuming ink and a paper.SOLUTION: The image forming device comprises: light emitting means that irradiates a nozzle surface of a head; image reading means that photographs the nozzle surface of the head; lifting means that lifts up the head; moving means that moves the light emitting means and the image reading means to immediate below the lifted-up head; image comparing means that compares image data of the nozzle surface with a preset reference value; and determining means that determines whether there is a discharge failure of a nozzle or not from results by the image comparing means.SELECTED DRAWING: Figure 1 【課題】インクや紙を消費せずにノズルの吐出不良を検出すること。【解決手段】ヘッドのノズル面を照射する発光手段と、ヘッドのノズル面を撮影する画像読取手段と、ヘッドを上昇させる昇降手段と、上昇後のヘッドの真下に発光手段及び画像読取手段を移動させる移動手段と、ノズル面の画像データと予め設定された基準値とを比較する画像比較手段と、画像比較手段の結果からノズルの吐出不良の有無を判断する判断手段と、を備える。【選択図】図１
