    摘要: An image forming apparatus that transfers an image from an image carrier onto a sheet passing between the image carrier rotating and a transfer member includes a fixing unit configured to thermally fix the image on the sheet while nipping and conveying the sheet with a pair of fixing members after the transfer, at least one of the fixing members rotating; a measuring unit configured to measure surface movement speed of the sheet in a non-contact manner while the sheet is being conveyed by the fixing members; and a control unit configured to control rotation speed of the fixing members in accordance with a result of the measurement, to adjust speed of conveyance of the sheet to a target speed determined beforehand for peripheral speed of the image carrier, the control being performed while the sheet being conveyed is in contact with the transfer member and the fixing members.

    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.
