PROBLEM TO BE SOLVED: To prevent temperature rise in a developing device and a cleaner caused by the heat of double-sided paper passing through and to prevent the faulty carrying of toner and a faulty image caused by the melting of the toner. SOLUTION: The heat absorption part of a heat pipe is disposed on the inside of a bending part which easily comes into contact with the paper in a passing-through type double-sided carrying path. The heat radiation part of the heat pipe is cooled by a fan or it is disposed on a deck so that it is utilized as the heat of a heater for preventing the moisture absorption of the sheet. By disposing heat insulating material between the double-sided carrying path and a deck heater, the heat of the deck heater is prevented from being transmitted to the double-sided carrying path. |
