Patent

CA 2102977

The present invention relates to a fixing device for use in image recording apparatuses, wherein the toner-adhering face of a sheet (100) onto which toner has been transferred is heated by a heating roller (30) to fix the toner. A pressure roller (20), pressing itself against the heating roller, assists in the heat-fixing process. In order to compensate for the curl resulting from the heat of the heating roller (30), a curl correcting roller (40) heats the back side of the sheet (100) with heat transmitted from the heat conducting part (31) of the heating roller (30) to another heat conducting part (41). This configuration dispenses with a built-in heat source which the curl correcting roller (40) would otherwise need.
