Patent Images
1. A cooling device, comprising:
- a cooling roller that comprises a hollow tubular member;
a cooling medium transport unit that transports a cooling liquid to an inside of the hollow tubular member; and
a turbulence generating unit that has a helical shape in a single winding direction and is disposed near an inner wall of the hollow tubular member to generate turbulence in the cooling liquid,wherein the cooling device is configured to cause the cooling roller to contact a sheet-like member to cool down the sheet-like member,wherein a winding direction of the helical shape is set to cause feeding in a direction reverse to a flow direction of a cooling liquid flowing near the inner wall of the hollow tubular member.
