PROBLEM TO BE SOLVED: To provide a cooling device having a liquid cooling system, which is properly controlled according to the use of an image forming apparatus and is free from waste and highly efficient, and to provide an image forming apparatus having the same. SOLUTION: A controller controls the cooling abilities of heat exchangers 32A, 32B and 32C to be controlled. That is, the controller performs control so that: when there is any heat exchanger in which a temperature rise is great in heat generating member to be cooled, the heat absorbing action of the heat exchanger is increased; and when the temperature rise of the heat generating member to be cooled is small, the heat absorbing action of the heat exchanger is decreased. Specifically, the controller controls the amount of a circulation liquid supplied to each heat exchanger by a pump 31, quantities of air sent by the cooling fans 34A and 34B of a radiator 33, and supply or non-supply of the circulation liquid to each heat exchanger. Accordingly, the cooling abilities of the heat exchangers 32A, 32B, and 32C are changed according to the operating conditions of the image forming apparatus. COPYRIGHT: (C)2009,JPO&INPIT |
