<P>PROBLEM TO BE SOLVED: To provide an image forming device preventing an excessive increase in temperature in a part close to a fixing device in a junction pipe conduit even after an air current forming fan is stopped under a condition that the fixing device is still in a state of high temperature. <P>SOLUTION: Branch pipe ducts 3d and 3e configured vertically from a junction pipe conduit 8 along a branch pipe conduit 9 cause natural convection and exhaust the air of which temperature has increased, in a junction pipe duct 4 of double pipe structure out of the housing through openings 2d and 2e. Outside air flows into the junction pipe duct 4 through an air inlet 4g of the junction pipe duct 4 and cools the junction pipe conduit 8 inside. <P>COPYRIGHT: (C)2010,JPO&INPIT |
