PROBLEM TO BE SOLVED: To provide a cooling device that improves cooling efficiency of a sheet member by a cooling roller, and to provide an image forming apparatus. SOLUTION: In the cooling device 18 including the cooling roller 22 that includes an outer tube 1 or the like, which is a hollow tubular member, and a cooling medium transport means 100 for transporting a coolant to the inside of the cooling roller 22, and bringing a paper 20, which is the sheet member, into contact with the cooling roller 22 to cool down the paper 20, a turbulence generating means such as a coil-like member 2 that generates turbulence in the coolant is provided near an inner wall of the outer tube 1.
