Abstract:
1. An image forming device that thermally fixes an unfixed image onto a recording sheet having the unfixed image formed thereon, by passing the recording sheet through a fixing nip between a pair of rotating members for applying pressure to the recording sheet, wherein in a standby state, rotation of the pair of the rotating members is controlled to stop, and a temperature of at least one of the pair of the rotating members is controlled to be kept at a given standby temperature, and in a low-temperature fixing state, the pair of the rotating members is controlled to rotate, and the temperature is controlled to be kept at a temperature lower than the standby temperature, in a high-temperature fixing state, the pair of the rotating members is controlled to rotate, and the temperature is controlled to be kept at a temperature higher than or equal to the standby temperature, the image forming device comprises: a determiner comprising: a controller operable, if the determination by the determiner is affirmative, to control the temperature to be kept at a temperature being intermediate between the lower temperature and the standby temperature, and subsequently to control the temperature to be kept at the standby temperature.
