摘要： A cylindrical fixing member for use with a fixing device includes a heat generating layer and an electrode layer contacting the heat generating layer. The electrode layer is smaller in volume resistance value than the heat generating layer. The electrode layer is formed in a helical shape so that a helical axis thereof extends in a direction along a generatrix direction of the fixing member. One end and the other end of the electrode layer are electrically open.

The plural unit circuits each includes a heating body that heats the rotating member, a resistive element that is connected in series to the heating body and has a positive temperature coefficient, and a parallel circuit that is connected in parallel to the resistive element. The unit circuits are each configured such that, if a resistance value of the resistive element is increased with a rise of temperature of the resistive element, a current flows through the parallel circuit.

摘要： A heating device includes a plurality of chip resistors, a conductor pattern, and a substrate. The plurality of chip resistors generate heat upon receiving power from a power source. The conductor pattern is arranged so as to serially connect the plurality of chip resistors. The conductor pattern is formed on the substrate. The conductor pattern connecting the chip resistors is wider in a forward path from the power source than in a backward path. The majority of the heat generated by the chip resistor is transmitted from the chip resistor to the conductor pattern, and the transmitted heat is radiated from the conductor pattern. Thus, not only the heat from the surface of the chip resistor but also the heat from the conductor pattern serves as heat source.

摘要： A control device includes an AC-DC converter that converts power supplied from a commercial power source into DC, a DC-DC converter that supplies the DC to a fixing heater, an calculator that calculates a target DC voltage of the DC to be supplied to the fixing heater, based on detected temperature of the fixing heater, an overcurrent detection unit that outputs an interruption signal when an overcurrent detection value is detected in a circuit including a switching element, and a controller that calculates switching time for switching the switching element so that an output of the DC-DC converter reaches the target DC voltage. When the interruption signal is output causing stopping of the switching of the switching element, the controller causes the calculator not to calculate the switching time to continuously use the previously calculated switching time after resuming switching of the switching element at a next switching cycle.
