Abstract
A fusing apparatus to fuse a toner image transferred to a printing medium by applying heat and pressure. The fusing apparatus includes a separation member that is rotatably mounted on a rotation axis to separate the printing medium from one of a heating roller and a pressing roller. The separation member includes a hollow portion into which the rotation axis is inserted, and a separation portion that contacts an outer circumference of the heating roller. The separation member is installed so as to be pitched around the rotation axis and a pitching axis having an inclination angle within a range of ±10° with respect to a line that connects a contact point between the separation portion and the outer circumference of the roller from which the printing medium is to be separated and a center of the roller from which the printing medium is to be separated.
