摘要： An image forming apparatus includes an image forming mechanism, a transfer mechanism, a fixing mechanism, and a heat radiation mechanism. The image forming mechanism forms a toner image which is transferred by the transfer mechanism transfers onto a recording sheet and is fixed by the fixing mechanism. The heat radiation mechanism is disposed between the image forming and fixing mechanisms and radiates heat generated by the fixing mechanism. The heat radiation mechanism includes a heat receiving member, a heat radiating member, and a heat conduction member. The heat receiving member receives heat generated by the fixing mechanism. The heat radiating member radiates the heat received by the heat receiving member. The heat conduction member has a thermal conductive property to efficiently conduct the heat from the heat receiving member to the heat radiating member.

摘要： Heat exhaust holes are provided in a unit frame at positions just above respective imaging units. An exhaust fan causes air heated at developing elements to be exhausted outside an apparatus via heat exhaust ducts and a common duct. The heat exhaust holes are formed in different sizes depending on a position of the imaging unit. The closer the position of the imaging unit is, the larger the heat exhaust hole provided above the imaging unit is.

摘要： The present invention provides an image forming apparatus which prevents the rusting of metallic components and paper jams and improves the cooling capability of a heat pipe by ensuring that water droplets do not become adhered to the heat pipe, thereby reducing thermal resistance. A fixing apparatus and a printer engine are shielded from each other by a heat receiving plate, a thermal insulation member, and a heat radiating plate. A heat pipe is provided in the shielding member. One end side of the heat pipe is disposed between the fixing apparatus and printer engine to serve as a heat receiving portion, and the other end side of the heat pipe is disposed in a higher position than the one end side to serve as a heat radiating portion. The thermal insulation member covers the periphery of an intermediate portion of the heat pipe between the two end sides of the heat pipe.
