摘要： In a fixing device of an image forming apparatus, at least one roller of a pair of rollers (14, 15) that come into pressure contact with each other is regulated so that outer diameter of the roller is 80 to 120 mm and total length of the roller (length in the axial direction) is 470 to 600 mm, and the roller is driven and rotated at the number of revolutions of 60 to 300 rpm by fitting a key groove (14c) formed at an end of the roller to a drive key (27a) provided for a drive force-transmitting shaft. Further, average thickness of core metal material (14a) of the fixing roller is regulated so that the moment of inertia in a direction of a rotational shaft of the fixing roller is 70 Kg·cm2 and less.

摘要： A tandem printing system that can achieve stable web conveyance, regardless of the configuration of a tandem printing system or the type of a web, by preventing malfunctions including a broken web that may occur when slack in a web occurs at the time the printing operation stops and the slack is then eliminated after the printing operation has started.By executing low-speed conveyance of web by a web feeding mechanism before the printing operation begins, slack W22a, W10a, and W15a in the web located downstream of the guide rollers, and the slacked web is accumulated in the air loop portion, thereby completing the standby for printing. At that time, the amount of web conveyance (accumulation) is saved. Then, high-speed printing operation begins, and when the amount of printing has reached the amount of web conveyance saved, high-speed conveyance by the web feeding mechanism begins.
