To provide an inkjet printing machine configured so as to prevent a conveying roll from corroding, even if a chlorine compound adheres to the conveying roll when a pre-coated printing base material is conveyed.SOLUTION: An inkjet printing machine 1 comprises a plurality of conveying rolls 6R (61, 62 and 63), 7R and 8R and a printing part 4. The plurality of conveying rolls 6R (61, 62 and 63), 7R and 8R convey a printing base material having a pre-coated layer formed on a coating surface. The printing part 4 forms an image by making an ink agent adhere to the coating surface. The pre-coated layer contains a chlorine compound. Rolls 61B, 62B and 63B and the conveying roll 8R which are arranged at the coating surface side of the plurality of conveying rolls 6R (61, 62 and 63), 7R and 8R are rubber rolls.SELECTED DRAWING: Figure 1 【課題】プレコート加工された印刷基材が搬送されることによって搬送ロールに塩素化合物が付着したとしても、搬送ロールの腐食を防止することが可能なインクジェット印刷機を提供する。【解決手段】インクジェット印刷機１は、複数の搬送ロール６Ｒ（６１，６２，６３），７Ｒ，８Ｒと、印刷部４と、を備える。複数の搬送ロール６Ｒ（６１，６２，６３），７Ｒ，８Ｒは、塗工面にプレコート層が形成された印刷基材を搬送する。印刷部４は、塗工面にインク剤を付着させて画像を形成する。プレコート層は、塩素化合物を含有する。複数の搬送ロール６Ｒ（６１，６２，６３），７Ｒ，８Ｒのうち塗工面の側に配置されるロール６１Ｂ，６２Ｂ，６３Ｂ及び搬送ロール８Ｒは、ゴムロールである。【選択図】図１
