Abstract
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.
Claims15
A fusing device comprising:
- 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,
- wherein 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.
An image forming apparatus comprising:
- a photosensitive body;
- a transfer roller to contact the photosensitive body to form a transfer nip to transfer a toner image on the photosensitive body to a printing medium;
- and
- a fusing device to fix the transferred toner image to the printing medium,
- wherein the fusing device comprises:
- a heating roller rotatably arranged,
- a pressing roller to contact the heating roller to form a fusing nip, and
- a guide member to guide the printing medium to the fusing nip after the printing medium passes the transfer nip,
- wherein an end of the guide member is disposed closer to the heating member than to the pressing member, with respect to an imaginary line extending from the fusing nip,
- wherein a distance from the end of the guide member to an outer circumferential surface of the heating roller increases as the end of the guide member extends from a center thereof to opposite sides thereof.
