Fixing device and image forming device having same

A fixing device to apply heat and pressure to a printing medium, comprising:

• a fixing belt to deliver heat to a surface of the printing medium;
• a rotating member to be in engagement with an outer circumferential surface of the fixing belt, to form a fixing nip between the fixing belt and the rotating member;
• and
• a nip forming member to press an inner circumferential surface of the fixing belt,
• wherein the nip forming member includes a protrusion protruding from a lower surface of the nip forming member to be in contact with the inner circumferential surface of the fixing belt, to press the inner circumferential surface of the fixing belt, at an outlet side of the fixing nip.

A fixing device to apply pressure to a printing medium for an image forming apparatus, comprising:

• a fixing belt arranged to be rotatable;
• a rotating member arranged to be in engagement with an outer circumferential surface of the fixing belt;
• a nip forming member to press the fixing belt, to form a fixing nip between the fixing belt and the rotating member;
• and
• a separation member arranged adjacent to the fixing nip, to separate the print medium from the fixing belt, the separation member having
• a first end arranged closer to the fixing belt than to the rotating member and a second end arranged closer to the rotating member than to the fixing belt.
