PROBLEM TO BE SOLVED: To realize a roller bias potential being the measure of a fixing offset with simple constitution in an induction heating fixing unit. SOLUTION: In this induction heating fixing unit, an induction heating coil is arranged in the inside of a conductive heating roller and lines of electric force which are generated when a high frequency current is made to flow through the coil are introduced into a bias potential generating circuit from the electricity collecting member arranged in the inside of the roller and DC potential which is generated and outputted from the bias generated circuit is supplied to the heating roller by a sliding electricity feeding member and it is made to be the bias of the fixing roller.
