PROBLEM TO BE SOLVED: To provide a medium fixing device and an image forming device of applying the same, capable of effectively restraining turning-over and floating of a recording medium, by stably fixing and holding the recording medium of various kinds and sizes. SOLUTION: This medium fixing device has a tip suction groove for sucking a tip area of a sheet-like medium. The tip suction groove is divided in the drum axis direction, and communicates with a tip drum groove in the drum axis direction via an orifice part with every divided area. By dividing the tip suction groove in response to a width to the recording medium, large and small recording media can be surely fixed. When having the tip suction groove on both of the tip side and the central side of the tip drum groove, flow passage resistance of the orifice part on the tip side is reduced more than the orifice part on the central side, so that a much flow rate is supplied by the tip suction groove on the tip side, and the tip area can be further strongly sucked.
