PURPOSE:To prevent oil from pooling by coating a fixing roll with the oil through an intermediate member when the intermediate member is at an abutting position. CONSTITUTION:The switch SW of the solenoid 10 of an oil coater is operated associatively with the power switch of a copying machine and turns off when the power switch is turned off, and an intermediate roll 8 is held at the abutting position through the operation of a tension spring. Then, the oil 4 in a storage tank 5 is supplied to the intermediate roll 8 through felt 7 from a supply port 6 and the intermediate roll 8 is driven to apply the oil to a heat roll 1. When the power switch is turned off and the switch SW is turned on, the solenoid 10 is excited to move the intermediate roll 8 to a separation position along a long-sized hole 9 and the oil coater 3 leaves the heat roll 1. The oil coater 3 coats the heat roll 1 with the oil 4 through the intermediate roll 8 when the power switch of the copying machine is on. Consequently, the oil is prevented securely from pooling between a couple of fixing rolls. |
