Filed: 1987-02-02
Abstract: PURPOSE:To surely and rapidly allow a fixing heater to respond to ON/OFF control by differentiating an ON/OFF signal for controlling them driving of fixing heater and integrating a phase-inverted signal to turn on/off the fixing heater. CONSTITUTION:When +24V is raised when a control circuit 1 is in a high level output (open collector), the base current of a transistor (TR) 1 is allowed to flow by a current flowing through resistors R1, R2 and capacitor C1 and a current flowing through a resistor R3, the TR 1 is turned on, the collector of the TR 1 is brought to a low level and a capacitor C2 is not charged. Namely, the TR 2 is kept at OFF and a fixing heater 2 is not lighted up. Since the capacitor C2 is not directly charged by a differential output from a differentiating circuit constituted of the C1 and a diode D1, but is charged by the collector output of the TR 1 through an inversional amplifier circuit constituted of resistors R3, R4 and the TR 1, the charging time is fast and the response time up to the ON of the heater 2 can be shortened.
