Abstract: An image forming apparatus for forming an image with a fixing member, which fixing member includes a first heating member and a plurality of second heating members is disclosed. The image forming apparatus includes a capacitor, a charging part for charging the capacitor, a first drive part for lighting on/off the first heating member by controlling a first power supply to the first heating member, a second drive part for lighting on/off at least one of the plurality of second heating members by controlling a second power supply to the plurality of second heating members, and a control part for dividing the plurality of second heating members into groups and permitting at least one of the groups to receive the second power supply during a waiting period of the image forming apparatus.

Abstract: An auxiliary power supply unit, which is attachable to and detachable from an apparatus, includes a charge unit configured to store electric charge, a terminal configured to establish electrical connection for discharge with the apparatus, and a discharge unit situated between the charge unit and the terminal to provide a discharge path that electrically connect the charge unit to the apparatus, the discharge path having an open/closed state thereof controlled during a period when an electric power is supplied from the apparatus, the discharge path being opened in response to a stoppage of supply of the electric power from the apparatus.

Abstract: A power source control apparatus including a capacitor; a charge control circuit for controlling a charger that charges the capacitor; a discharging circuit for discharging power charged in the capacitor to a heating member for heating. The power source control apparatus is shifted to an energy saving mode in which power supply to a part of power loads is stopped when a first condition is satisfied, and the power source control apparatus terminates the energy saving mode when a second condition is satisfied. In the apparatus, the charge control circuit is supplied with power from a power source circuit that supplies power during the energy saving mode.

Abstract: A main controller controls a capacitor charger to charge a capacitor as necessary. A sub-controller controls a power saving mode and stops a power supply to the main controller when shifting to the power saving mode. A charge control circuit compares a terminal voltage of the capacitor with a predetermined value by a comparator circuit. If the terminal voltage is lower than the reference value, an AND circuit takes a logical product of an output signal of the comparator circuit and a power saving signal indicating the shift to the power saving mode, and outputs a control signal indicating an instruction to charge the capacitor, to the capacitor charger.

Abstract: A fixing roller in an image forming apparatus (such as a copier) has a fixing heater that is supplied power from a capacitor. The fixing heater, the capacitor, a mechanical switch (such as a relay) and a semiconductor switch (such as a FET) are serially connected. As a cover of the apparatus is opened, an interlock switch is turned on and outputs an off-signal to a CPU, which turns off the semiconductor switch prior to turning off the mechanical switch, and thereby prevents a counter-electromotive voltage due to an inrush current.
