Abstract
A fixing device includes a leading-end fixing value output part to output a leading-end fixing value indicating a leading-end fixing temperature and a leading-end separation value output part to output a leading-end separation value indicating a leading-end separation temperature. These output parts both output a higher value as a leading-end toner value representing a toner adhesion amount of a toner image in a leading area of a sheet is higher. A controller of the fixing device performs separation control to control a heating temperature by a heating source so that a leading-end set temperature at a fixing nip while the sheet leading area is passing through the fixing nip becomes equal to or higher than the leading-end fixing temperature. When the leading-end fixing value is lower than the leading-end separation value, the leading-end set temperature becomes equal to or higher than the leading-end separation temperature.
