Title: Image forming device
Inventor: NAKAMURA JUNICHI
IPC: B41J29/377
Filed: 2000-05-08
Abstract: PROBLEM TO BE SOLVED: To provide an image forming device equipped with a means for efficiently cooling, with low power consumption, a high voltage conversion circuit variably outputting high voltage required to form an image. SOLUTION: By input of a PWM: pulse width modulation signal 7, an output conversion part 2 turns on/off a transistor 3 and drives the transformer of a conversion part so as to output high voltage. The transistor 3 and the transformer of the conversion part are forcibly cooled by a fan in accordance with the operation state of the high voltage conversion circuit. By using a PWM output ON-signal 6 generated synchronously with the output of the PWM signal 7 over the output period of the signal 7 in a CPU1 as a control signal for a transistor 5 and turning on the transistor 5 in the output period, a fan motor 4 is driven. Thus failures caused by the absence of cooling means are eliminated.
