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 .
