PROBLEM TO BE SOLVED: To provide an image formation device which enables energy saving by switching a fixing temperature and enables maintenance of reproducibility of an image of an encoded discriminator.SOLUTION: In an image formation device, a target temperature at which a heating roller should be kept can be switched at least between a first fixing temperature and a second fixing temperature that is higher than the first fixing temperature. In a case where an image of encoded discriminator is contained in an image of an amount of single page (YES in step S104), a position in a paper passing direction on a recording sheet where the image of encoded discriminator is formed is obtained (step S105). During a period in which a toner image within a range where the image of encoded discriminator is formed is being fixed, switching of the target temperature is executed at a timing by which a temperature of the fixing member becomes the second fixing temperature (steps S110, S111). |
