摘要： A toner image fixing device includes a heat roller, and a backup roller engaged with the heat roller to form a nip therebetween. A paper carrying a toner image is passed through the nip whereby the toner image is thermally fused and fixed on the paper. The heat roller, which is stained by a part of the fused toner during the fixing process, should be cleaned before a toner image is fixed on a successive paper without staining. To this end, a cleaning roller made of a felt material is pressed against the heat roller so as to be rotated together with the heat roller by a frictional force acting therebetween. The cleaning roller must be periodically replaced. The fixing device is constituted such that the replacement of the cleaning roller can be easily and quickly carried out.

摘要： It is an object of the present invention to prevent temperature decrease in a border portion of each of heating coils and to enable to eliminate an influence given by the change in a load state. In order to attain this object, an induction heating unit 400 according to the present invention is provided with control units 420 (420a to 420d) respectively corresponding to a plurality of heating units 310 (310a to 310d). A phase detector 424d of the control unit 420d obtains a phase difference between an output current (heating coil current IL4) of an inverter 314d detected by a current transformer 160d and a reference signal outputted by a reference signal generating section 426, and inputs it to a drive control section 422d. The drive control section 422d adjusts an output timing (phase) of a gate pulse to be given to the inverter 314d so as to make a phase of the heating coil current IL4 of the inverter 314d coincide with a phase of the reference signal outputted by the reference signal generating section 426. A phase control section 334d controls a variable reactor 326d so as to make the phases of an output voltage and the output current (heating coil current IL4) of the inverter 314d coincide with each other, and improves a power factor of the inverter 314d. Each of the other control units 420a to 420c also performs the same control operation.
