PROBLEM TO BE SOLVED: To provide a fixing device constituted so that plural cross-flow fans can be coupled by such simple constitution that the number of parts is small and abnormal noise, rotational irregularity or the like are prevented from occurring when the temperature of a device main body rises. SOLUTION: The cross-flow fans 6a and 6b are serially coupled and one fan 6a positioned at the outermost end is coupled to a driving source 11 outside it. Then, the mutual coupling part of the fans 6a and 6b and the coupling part of the fan 6a and the driving source 11 are provided with spring means 20a and 20b acting so as to press the plural fans 6a and 6b toward a fitting wall 17c set at a position being most distant from the driving source 11.
