摘要：A fusing device and an image forming apparatus including the fusing device are provided, the fusing device having a structure that ensures a stable transport of a printing medium by preventing a printing medium from deviating from a transport path between a transfer nip and a fusing nip. The fusing device includes a heating member, a pressing member to contact the heating member to form a fusing nip, and a guide member to guide a printing medium to the fusing nip. An end of the guide member is shaped such that a height of the end decreases as the end extends from a center thereof to opposite sides thereof, and disposed closer to the heating member than to the pressing member, with respect to an imaginary line extending from the fusing nip.

主权项：1. A fusing device comprising: a heating member; a pressing member to contact the heating member to form a fusing nip; and a guide member including a guiding part to guide a printing medium to the fusing nip, wherein an end of the guiding part of the guide member is shaped such that a height of the guiding part decreases as an end of the guiding part extends from a center thereof to opposite sides thereof, and the end of the guiding part faces the heating member and is disposed closer to the heating member than to the pressing member, with respect to an imaginary line extending from a center of the fusing nip in a direction parallel to a surface of the heating member contacting a surface of the pressing member to form the fusing nip, the guiding part forming at least one portion of a transport path of the printing medium in a substantially vertical direction, wherein a closest distance between the heating member and an edge of the end of the guiding part, which faces the heating member, that is farthest from the pressing member is between about 0.5 mm and about 1.5 mm, and wherein a difference in height between the center of the end of the guiding part and the opposite sides of the end of the guiding part is between about 2.5 mm and about 3.5 mm.
