摘要： An image forming apparatus includes a developing device; a temperature detecting unit measuring a temperature of a main body; a cooling unit cooling the inside of the image forming apparatus; and a controller controlling the cooling unit based on result of the temperature detecting unit. The controller increases an air flow rate of the cooling unit such that the air flow rate is higher than a predetermined rate if the result of the temperature detecting unit is higher than a first temperature during non image forming and the controller increases an air flow rate of the cooling unit such that the air flow rate is higher than the predetermined rate if the result of the temperature detecting unit is higher than a second temperature which is higher than the first temperature during an image forming operation.

摘要： A fixing device includes a first feeder provided downstream of a fixing portion heating a toner image formed on a first side of a sheet in a feeding direction, a second feeder provided adjacent downstream of the first feeder, and a guide contacting with a second side of the sheet fed by the first feeder and guiding toward the second feeder, a blower, a first duct guiding the air at a first position between the first and feeders, and a second duct at a second position between the first position and the first feeder. The first and second feeders are contactable to the sheet over an entire width. The air from the blower passes through the first duct, is sent to a feeding passage formed between the first and second feeders from the first position, and sent to the second side, then, the air passes through the second duct from the feeding passage via the second position and is exhausted.
