ABSTRACT:
In a sheet heating device for heat-fixing an image on a sheet comprising a sheet guide plate for guiding a sheet therethrough, a pair of sheet feed rollers provided at the upstream of the sheet guide plate for supplying the sheet to the sheet guide plate, a pair of sheet discharge rollers provided at the downstream of the sheet guide plate for discharging the sheet to an outside, and a cover case including a heater for heating air and heating the sheet with the heated air and a blower fan for circulating the heated air through the inner portion of the cover case and the sheet guide plate, plural capillary projections having a lower thermal conductivity than the sheet guide plate are provided at least on the front surface of the sheet guide plate to thereby prevent the sheet from directly contacting the sheet guide plate, or an arcuate member is provided in the cover case to homogeneously guide the heated air over the sheet guide plate to thereby homogeneously heat-fix an image on the sheet.
