A fuser device includes: a fuser member that heats developer on a print medium; a pressure member that presses the fuser member so as to provide a contact region therebetween; and a separation member that separates the print medium, which is ejected from the contact region, from either the fuser member or the pressure member. The separation member includes a separator in a plate-like shape and a support member that supports the separator such that the separator is disposed in the vicinity of the fuser member. The separator includes a planar part in a plate-like shape that is sustained by the support member; a tip part that is a tip of the separator, an inclined surface part that is inclined toward the tip part in a thickness direction of the separator, a border part that is defined as a boundary between the planar part and the inclined surface part.
