PURPOSE:To form a fixing member with a small consumption of electricity by providing a pressuring electrode member by which a recording medium is pressurized and crimped between an outer periphery surface of a heat generating member and a medium conducting member. CONSTITUTION:A fixing roll 25 is pressured to a facing roll 27 which is the medium conducting member by an electrode roll 26 which is a pressuring electrode member placed in the inner periphery part of the fixing roll 25. Then, when a fixing part is reached by a printing paper 23 on which a transferred image is adhered, each rolls 25 to 27 are rotated in a specified direction by an electrode roll 26 through a gear construction 40, etc., and electrical current is passed to the electrode roll 26 from a power source part 43. At this time, since a heat generating resistance body layer 28 of a fixing roll 25 is energized in parts positioned between the two rolls 26 and 27, heat is generated only in a part facing the printing paper 23, and the surface temperature reaches a necessary value for fixing with minimum energizing time. Thus, the fixing device with an extremely short warming up time and small electricity consumption can be obtained. |
