Abstract

A sheet heating device includes a heater, a power supply for the heater, a temperature sensor configured to detect the temperature of the heater, and a control unit configured to set an initial powersupply level of the power supply at a start of a sheet heating job by the heater based on the sheet heating job and according to whether or not maximum and minimum power supply levels from a last sheet heating job are stored, and control the power supply level of the power supply during the sheet heating job based on a temperature detected by the temperature sensor.

Description

technical field [0001] This specification relates to temperature control technology for paper heating. Background technique [0002] In the prior art, there is known a paper heating device that supplies a large amount of power to a heater to quickly raise its temperature to a predetermined temperature during start-up, image fixing, or image decolorization. In the conventional paper heating apparatus described above, since a large amount of electric power is supplied, the variation of the heater temperature generated by the heater tends to become large. [0003] For example, when the paper heating device is turned on after it has been turned off or entered sleep mode, a large amount of power is supplied to the heat source to rapidly increase the temperature of the heater to keep the paper heating device in a warm state. However, since the heater temperature at startup may be higher than its normal shutdown temperature, the large amount of power supplied may cause the heater ...
