Abstract:
A fixing unit comprising:a first fixing member having a heater and a heaterless second fixing member disposed to oppose said first fixing member to hold and advance a print medium therebetween in sandwiched relation;a first temperature detector which detects a surface temperature of said first fixing member and outputs a first signal indicative of the surface temperature of said first fixing member;a second temperature detector which detects a surface temperature of said second fixing member and outputs a second signal indicative of the surface temperature of said second fixing member, said second signal being attenuated by a selected attenuation coefficient to provide an attenuated signal;a controller combining the first signal with said attenuated signal to produce a third signal, the controller controlling energization of the heater in accordance with the third signal so as to maintain the temperature of said first fixing member to a target temperature.
