Abstract
A novel heating device includes a heating member configured to heat a sheet on an opposite face opposite a liquid applied face. The heating member has a curved portion along which the sheet is conveyed and warped so that the liquid applied face has a concave shape.
Claims22
A heating device, comprising:
- a belt which is a heating member configured to heat a sheet on an opposite face opposite a liquid applied face, the heating member having a curved portion along which the sheet is conveyed and warped so that the liquid applied face has a concave shape;
- a plurality of belt supports around which the belt is wound;
- a heater to heat the belt;
- a roller to press an outer circumferential surface of the belt between the plurality of belt supports to form the curved portion of the belt;
- and
- a projecting rotator having a plurality of projections projecting radially outward, the projecting rotator facing an outer circumferential surface of the belt.

A heating device, comprising:
- a belt to heat a sheet on an opposite face opposite a liquid applied face, the belt including:
- a curved portion along which the sheet is conveyed and warped so that the liquid applied face has a concave shape;
- an upstream portion along which the sheet is conveyed to the curved portion;
- a downstream portion along which the sheet is conveyed from the curved portion, the downstream portion begins immediately after the curved portion, and ends where the sheet is separated from the belt,
- wherein:
- the belt is a single continuous belt which includes the upstream portion, the curved portion, and the downstream portion,
- the upstream portion is longer than the downstream portion,
- the heating device further comprising a rotator facing an outer circumferential surface of the upstream portion, the rotator to press the sheet against the outer circumferential surface of the upstream portion so that the belt at the upstream portion heats the opposite face of the sheet longer than the belt heats the opposite face of the sheet at the downstream portion.

A heating device, comprising:
- a belt to heat a sheet on an opposite face opposite a liquid applied face, the belt including:
- a curved portion along which the sheet is conveyed and warped so that the liquid applied face has a concave shape;
- and
- an upstream portion along which the sheet is conveyed to the curved portion, the upstream portion begins at a portion of the belt which initially contacts the sheet, and ends where the curved portion of the belt begins,
- the heating device further comprising a sheet affector which causes the sheet to contact the upstream portion,
- wherein:
- the sheet is contacted by the sheet affector and heated at the upstream portion by the belt without contacting another belt at the upstream portion.
