Title:
INDUCTION HEATING ROLLER DEVICE, FIXING DEVICE USING THIS AND IMAGE FORMING DEVICE
Document Type and Number:
WIPO Patent Application WO/2004/105442
Kind Code:
A1
Abstract:
An induction heating roller device comprising a high-frequency power source device (HFS) provided with a main circuit unit (MC) for converting a low-frequency ac voltage into a high-frequency ac voltage to output the result and with a control unit (CC) for controlling the main circuit unit (MC) and being capable of outputting a high-frequency ac voltage PWM-controlled at a frequency sufficiently higher than that of a low-frequency ac voltage and sufficiently lower than that of a high-frequency ac voltage, an induction coil (IC) to which the high-frequency ac voltage of the high-frequency power source device (HFS) is applied, and a heating roller (HR) for allowing a secondary current to flow to effect heating by being magnetically coupled with the induction coil (IC).
