Abstract

A heating device includes a heating unit that heats in a non-contact manner an upper surface of a transport material that is transported, and a blowing unit that blows air against a lower surface of the transport material via a blowing hole that is provided in an opposing surface opposing the lower surface of the transport material, the opposing surface being obliquely disposed with respect to a horizontal direction.

First claim

What is claimed is:

1. A heating device comprising:
a heating unit that heats in a non-contact manner an upper surface of a transport material that is transported; and
a blowing unit that blows air against a lower surface of the transport material via a blowing hole that is provided in an opposing surface opposing the lower surface of the transport material, the opposing surface being obliquely disposed with respect to a horizontal direction,
wherein the opposing surface is obliquely disposed by causing a downstream side of the opposing surface in a transport direction of the transport material to be disposed at a position that is higher than a position of an upstream side of the opposing surface in the transport direction of the transport material.

2. The heating device according to claim 1 , wherein the transport material is transported with a downstream-side portion of the transport material in the transport direction being held and without an upstream-side portion of the transport material in the transport direction being held, and
wherein the opposing surface is disposed at an angle at which the upstream-side portion of the transport material in the transport direction contacts the opposing surface when the blowing unit is not blowing air.

3. The heating device according to claim 2 , wherein the blowing unit blows air also when the transport material is not being transported.

4. The heating device according to claim 1 , wherein a blowing direction of the blowing unit is toward a low side of the opposing surface.

5. The heating device according to claim 2 , wherein a blowing direction of the blowing unit is toward a low side of the opposing surface.

6. The heating device according to claim 3 , wherein a blowing direction of the blowing unit is toward a low side of the opposing surface.

7. The heating device according to claim 1 , further comprising:
an accommodation unit that is provided on a low side of the opposing surface and that accommodates the transport material that has fallen from the opposing surface.

8. The heating device according to claim 2 , further comprising:
an accommodation unit that is provided on a low side of the opposing surface and that accommodates the transport material that has fallen from the opposing surface.

9. The heating device according to claim 3 , further comprising:
an accommodation unit that is provided on a low side of the opposing surface and that accommodates the transport material that has fallen from the opposing surface.

10. The heating device according to claim 4 , further comprising:
an accommodation unit that is provided on a low side of the opposing surface and that accommodates the transport material that has fallen from the opposing surface.

11. An image forming apparatus comprising:
an image forming unit that forms an image on a recording medium serving as a transport material; and
the heating device according to claim 1 that in the non-contact manner heats the upper surface of the transport material on which the image has been formed by the image forming unit.

12. A heating device comprising:
a heating unit that heats in a non-contact manner an upper surface of a transport material that is transported; and
a blowing unit that blows air against a lower surface of the transport material via a blowing hole that is provided in an opposing surface opposing the lower surface of the transport material, the opposing surface being obliquely disposed with respect to a horizontal direction,
wherein the blowing unit blows air also when the transport material is not being transported.
