Abstract: A fixing device includes: a fixing member that heats a toner image formed on a recording sheet in order to fix the toner image on the recording sheet; a pressurizing member that nips the recording sheet together with the fixing member to pressurize the toner image on the recording sheet; a heater that heats the pressurizing member; and a hardware processor that controls a heating temperature of the pressurizing member by the heater, wherein the hardware processor acquires setting of glossiness of the toner image and controls the heating temperature to be higher as the glossiness in the setting is lower.
