<p><P>PROBLEM TO BE SOLVED: To provide an image forming device, an image forming method, and an image forming system for performing second fixation processing satisfactorily, even if the speed of a sheet passing through a second fixing device is higher than the speed of a sheet passing through a first fixing device. <P>SOLUTION: In this image forming method, speed of sheet in the second fixing device is made higher, by setting it to transport speed V3 of paper being higher than transport speed V1 of ordinary paper delivery mode in inversion paper delivery mode for inverting paper by an inversion part, and temperature of a fixing roller or pressure of a pressurizing roller in at least the second fixing device is raised. For example, the temperature of the fixing roller in the second fixing device is raised to temperature t2 (temperature t2>temperature t1). Consequently, even if transport speed of sheet in the inversion part is increased, remaining molten toner for toner image and defective fixing can be prevented. Furthermore, since the image forming device can cope with the high speed transport of sheet, the second fixing device can be installed close to the inversion part, and the size of a device body can be reduced. Additionally, the temperature t1 is the temperature for heating the first fixing device. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
