摘要： An image forming apparatus 100 adds heat and pressure to a toner image formed on a sheet, fixes the toner image to the sheet. The apparatus 100 detects a temperature of an end of a fixing device 13, cools the end of the fixing device 13, controls a cooling level by a cooling device 51 in accordance with the temperature, predicts a discharge amount of ultra fine particles based on a parameter depending on the cooling level, controls an image forming operation such that the discharge amount of ultra fine particles is reduced in accordance with the discharge amount predicted.
