Abstract
The present invention concerns a fixing apparatus and an image-forming apparatus. The fixing apparatus and the image-forming apparatus include a heating roller; a heating element disposed in the heating roller; a pressing roller pressure-contacting the heating roller to fix an image onto a transfer sheet passing through a pressure-contacting section between the heating roller and the pressing roller; and a cooling device to cool the heating roller. In the fixing apparatus, the cooling device is activated during a predetermined time period after consecutive fixing operations are completed. While, the image-forming apparatus further includes a control section to activate the cooling device during a predetermined time period after consecutive fixing operations are completed.
