Abstract
Disclosed are a fixing device and an image formation device. The fixing device includes first and second sensors used to respectively detect first and second temperatures; first and second calculators used to respectively calculate, during a process of starting a heating source, first and second temperature gradients; a parameter storage used to store at least first and second temperature gradient thresholds; a determination part used to get a determination result; an information generation part used to generate, based on the determination result, restart prompt information indicating that the image formation device needs to be restarted because the voltage of an electrical source is too low; and an information transmission part used to transmit the restart prompt information to a display device.
