Abstract
A cooling device includes a shaft that rotatably extends adjacent to a fixing device, a blade device including a blade coupled to the shaft, and a housing to accommodate the blade device, the housing including an inlet to draw in air and an outlet disposed to direct the air toward a heating body of the fixing device.
Claims12
A cooling device comprising:
- a rotatable shaft;
- a pair of blade devices including a first blade device coupled to a first end of the shaft and a second blade device coupled to a second end of the shaft opposite the first end;
- and
- a housing to accommodate the blade device,
- wherein the housing includes an inlet to draw in air and an outlet disposed to direct the air toward a heating body of a fixing device;
- and
- a drive transmission member to transmit a driving force of a pressure roller of the fixing device to the shaft to rotate the shaft.

A fixing device comprising:
- a fixing unit including a rotatable heating body and a pressure roller that is rotatably pressed against the heating body;
- and
- a cooling device including:
- a shaft that rotatably extends adjacent to the fixing unit;
- a pair of blade devices including a first blade device coupled to a first end of the shaft and a second blade device coupled to a second end of the shaft opposite the first end;
- and
- a housing to accommodate the blade device,
- wherein the housing includes an inlet to draw in air and an outlet to open toward the heating body of the fixing unit;
- and
- a drive transmission member to transmit a driving force of the pressure roller of the fixing device to the shaft to rotate the shaft.
