A fixing device includes: a plurality of heating units which individually heat a plurality of areas of a fixing member; an acquisition unit which acquires information on an image forming range and a non-image forming range of the recording sheet for each of the plurality of divided heating areas; and a control unit which performs first control for controlling the corresponding heating unit such that a contact portion of the image forming range of the recording sheet has a target fixing temperature when the image forming range contacts the fixing member at the contact portion of the image forming range, and second control for controlling the corresponding heating unit such that a contact portion of the non-image forming range of the recording sheet has a temperature lower than the fixing temperature when the non-image forming range contacts the fixing member at the contact portion of the non-image forming range.

摘要:
The image forming device includes a reception unit, an image forming unit, a switching unit, a detection unit, and a charging unit. The switching unit switches the image forming device between a first mode in which the reception unit is not supplied a voltage from a power source, is supplied power from a secondary battery, and receives image forming requests, and a second mode in which the image forming unit is supplied the voltage and performs image forming. The detection unit detects a value of an amount of energy of the secondary battery. In the second mode, the charging unit charges the secondary battery by supplying the voltage to the secondary battery when the value is equal to or less than a threshold value, and the charging unit boosts the voltage and supplies the boosted voltage to the secondary battery when the value is greater than the threshold value.
