Abstract
A fusing device includes a rotary fusing part; a heating unit heating the rotary fusing part; a rotary pressure part pressed against the rotary fusing part; nozzles jetting compressed air to paper being conveyed through a nip between the rotary fusing part and the rotary pressure part; and separating parts guiding the paper separated from the rotary fusing part. The nozzles and the separating parts are disposed downstream of the nip in a paper conveying direction so as not to contact the rotary fusing part and the rotary pressure part and are arranged alternately along the length direction of the nip that is orthogonal to the paper conveying direction. The separating parts protrude beyond the tips of the nozzles toward the nip.

A fusing device, comprising:
- a rotary fusing part;
- a heating unit heating the rotary fusing part;
- a rotary pressure part pressed against the rotary fusing part;
- nozzles jetting compressed air to paper being conveyed through a nip between the rotary fusing part and the rotary pressure part;
- and
- separating parts guiding the paper separated from the rotary fusing part,
- wherein the nozzles and the separating parts are disposed downstream of the nip in a paper conveying direction so as not to contact the rotary fusing part and the rotary pressure part,
- wherein the nozzles and the separating parts are arranged alternately and spaced from each other along a length direction of the nip that is orthogonal to the paper conveying direction, and
- wherein the separating parts protrude beyond tips of the nozzles toward the nip.
A fusing device, comprising:
- a rotary fusing part;
- a heating unit heating the rotary fusing part;
- a rotary pressure part pressed against the rotary fusing part;
- nozzles jetting compressed air to paper being conveyed through a nip between the rotary fusing part and the rotary pressure part;
- and
- separating parts configured to function as a paper guide for guiding the paper separated by the compressed air from the rotary fusing part when the compressed air is being jetted from the nozzles and function as a separating plate for separating the paper from the rotary fusing part when the compressed air is not being jetted from the nozzles,
- wherein the nozzles and the separating parts are disposed downstream of the nip in a paper conveying direction so as not to contact the rotary fusing part and the rotary pressure part,
- wherein the nozzles and the separating parts are arranged alternately along a length direction of the nip that is orthogonal to the paper conveying direction, and
- wherein the separating parts protrude beyond tips of the nozzles toward the nip.
