Claim:
An image forming apparatus to heat and fix a toner image onto a print medium, comprising: an image forming section that forms the toner image on a surface of an image carrying body; a conveying section that conveys the print medium; a transferring section that transfers the toner image on the image carrying body onto the print medium conveyed by the conveying section; a fixing section that heats and fixes the toner image transferred onto the print medium; a fixing section temperature detection section that detects a temperature of the fixing section; an apparatus controlling section configured to control the temperature of the fixing section on the basis of a detection result of the fixing section temperature detection section; and an inner temperature detection section that detects an inner temperature of the image forming apparatus, wherein the inner temperature detection section is placed at a predetermined location outside of the image forming section so that the inner temperature detection section receives about the same quantity of heat as a toner accommodating section inside of the image forming section receives from the fixing section, the apparatus controlling section is further configured to control the temperature of the fixing section on the basis of a detection result of the inner temperature detection section.
