Abstract
A cooling apparatus includes: a stacker vessel in which a medium having a fixed visible image is ejected and stacked; and an eddy flow generating device that is arranged in an upper portion of the stacker vessel, and generates an eddy flow which flows along a surface of the medium transported into the stacker vessel to make an eddy and cools the medium.
Claims3
A image forming apparatus comprising:
- a heating device;
- and
- a cooling device comprising:
- a stacker vessel in which a medium having a fixed visible image is ejected and stacked;
- and
- an eddy flow generating device that is arranged in an upper portion of the stacker vessel, and generates an eddy flow which flows along a surface of the medium transported into the stacker vessel to make an eddy and cools the medium;
- an eddy current generating unit that floats the medium in the upper portion of the stacker vessel, and cools the medium,
- an image density determining unit determines whether or not the image density of the fixed visible image on the surface of the medium is higher than a predetermined image density, and
- an eddy current controlling unit controls, in a case where the image density on the surface of the medium is higher than the predetermined image density, the eddy current generating unit to increase volume of an air supplied from the eddy current generating unit,
- wherein the heating device includes a fixing device that fixes a non-fixed visible image carried on the surface of the medium.
