Relates to a fixing device comprising a fixing part for fixing toner to a
paper, and a separation mechanism to separate paper P from fixing body,
separation mechanism has a separation member 12 with a shaft member 17
and a separation pawl 16, and a first urging mechanism 19 for urging
separation pawl 16 to approach fixing body 2. To improve the device to
suitably separate even a firmly adhered paper without damaging fixing
body, a second urging mechanism 28 is provided for urging shaft member 17
toward initial position. Resultant force of pressing forces by two urging
member 19, 28 is set such that shaft member 17 will be moved to the
retracted position by a jammed paper P, and in a normal state, shaft
member 17 will be prevented from moving to the retracted position even if
paper P has a high adhesive force.
