Abstract
A fixing device includes a pair of rotating bodies forming a nip portion, for fixing an image formed on the surface of a sheet to the sheet; and a separating pawl having a leading end portion and a tailing end portion, a tip part of the leading end portion being made press contact with a surface of at least one of the pair of rotating bodies. The separating pawl includes a pivotal portion integrally formed between the leading end portion and the tailing end portion, and the tailing end portion has a spring property capable of adjusting the press-contact force of the tip part.
Claims23
A fixing device comprising:
- a pair of rotating bodies forming a nip portion, for fixing an image formed on a surface of a sheet;
- a separating pawl having a leading end portion and a tailing end portion, a tip part of the leading end portion being made in press contact with a surface of at least one of the pair of rotating bodies, and having a pivotal portion integrally formed between the leading end portion and the tailing end portion, the tailing end portion having a spring property capable of adjusting press-contact force of the tip part;
- a case accommodating the separating pawl and directly supporting the separating pawl rotatably through the pivotal portion of the separating pawl;
- and
- the pivotal portion of the separating pawl is formed into a cylindrical shape and wherein the case includes a shaft that passes through the pivotal portion of the separating pawl for directly supporting the separating pawl rotatably through the pivotal portion of the separating pawl.
