PROBLEM TO BE SOLVED: To increase the separating performance of a printing paper sheet, and reduce the installation place of a cleaning means. SOLUTION: This printing device is equipped with plate cylinders 40 and 50, pressing rolls 46 and 56, an upstream side belt carrying mechanism 7, and a downstream side belt carrying mechanism 8. In this case, the pressing rolls 46 and 56 press respective plate cylinders 40 and 50. In the upstream side belt carrying mechanism 7, a fed printing paper 45 is press- carried between the plate cylinder 40 and the pressing roll 46 on the upstream side, and an ink transfer is performed on the upper surface of the printing paper sheet 45. Also, the upstream side belt carrying mechanism 7 has a belt 62 and a suction fan 64 which are arranged on the discharging side of the printing paper sheet 45. In the downstream side belt carrying mechanism 8, the printing paper 45 fed by the upstream side belt carrying mechanism 7 is press-carried between the plate cylinder 50 and the pressing roll 56 on the downstream side, and an ink transfer is performed on the lower surface of the printing paper 45. Also, the lower side belt carrying mechanism 8 has a belt 67 and a suction fan 69 which are arranged on the discharging side of the printing paper 45. Then, one end side of the belt 67 of the downstream side belt carrying mechanism 8 is engaged with the pressing roll 56. Then, the pressing roll 56 is provided to be rotatable together with the movement of the belt 67. Also, a cleaning roll 70 is provided on the belt 67.
