Abstract

PURPOSE: To prevent the deformation of a fixing roller by reduering a lower roller positioned below rigid thermal rollers provided at the upper and lower sides of an elastic fixing roller to move up and down by means of the planetary gear mechanism in order to perform the fixing work, and desengaging depression at the time of stoppage of electric current.
