A fusing apparatus for an image forming apparatus includes a fusing belt having a sidewall that faces the fusing bel, a guide member, disposed on the sidewall and having a lower portion disposed above a lower portion of the bushing, and a ring member, disposed between the guide member and the fusing belt. The ring member can be deflected toward the sidewall in a gap which is provided below the lower portion of the guide member and between the ring member and the sidewall.

Fusing apparatus and image forming apparatus including the same

A fusing apparatus for an image forming apparatus includes a rotatable fusing belt, a bushing to guide the rotation of the fusing belt, a ring member provided between the bushing and the fusing belt, and a guide member, provided on an upper portion of a sidewall of the bushing that faces the fusing belt to support an upper portion of the ring member. A gap is provided between a lower portion of the guide member and a lower portion of the sidewall to allow deflection of a lower portion of the ring member toward the sidewall.

A fusing apparatus for an image forming apparatus includes a fusing belt which rotates, a bushing guiding the fusing belt, a ring member rotatably coupled to the bushing and in contact with the fusing belt so as to rotate together with the fusing belt, and a sliding guide member, provided between the ring member and the sidewall of the bushing and at least partially disposed above a central axis of the fusing belt. The sliding guide member slidably supports the ring member and protrudes from the sidewall of the bushing such that a continuous gap is provided from a bottom of the sliding guide member to a bottom of the sidewall of the bushing.

A fusing apparatus and an image forming apparatus includes: a fusing belt; a pressing roller pressed to the fusing belt to form a nib part and rotating the fusing belt; a bushing guiding an edge of the fusing belt; and a ring member rotatably coupled to the bushing and in contact with the edge of the fusing belt that rotates to rotate together with the fusing belt, wherein a first frictional force generated between the edge of the fusing belt and the ring member is larger than a second frictional force generated between the bushing and the ring member.
