It is an object of the present invention to provide an image-recording process and an image-recording apparatus, even at high density image and high speed image output, capable of suppressing the occurrence of curl in the final image sheet, and controlling and giving the desired direction and size of the curl. For this purpose, an image-recording process includes recording an image on an image-recording material which includes a thermoplastic resin contained layer on a support, heating the image-recording material to a temperature higher than a glass transition temperature of thermoplastic resin in the thermoplastic resin contained layer, controlling the curl by contacting a curl controlling member with at least a part of the image-recording material, and cooling the image-recording material to a temperature below the glass transition temperature of the thermoplastic resin.

The image-recording process according to claim 1, wherein the thermoplastic resin contained layer is at least any one selected from an image-receiving layer, a color material layer, an intermediate layer, a support, a backing layer, and a combination thereof. 3. The image-recording process according to claim 1, wherein a glass transition temperature of the thermoplastic resin is 40�� C. to 100�� C. 4. The image-recording process according to claim 1, wherein the curl controlling member is contacted with the image-recording material at a temperature ��10�� C. of a glass transition temperature of the thermoplastic resin. 5. The image-recording process according to claim 1, wherein at least any one of a direction of the curl and a size of the curl is controlled. 6. The image-recording process according to claim 1, wherein the curl controlling member comprises a curved shape on its surface, and the curl is controlled by changing at least any one of a curvature radius and a curved length of the curved shape. 7. The image-recording process according to claim 1, wherein the support comprises a raw paper and a polyolefin resin layer disposed on at least one surface of the raw paper. 8. The image-recording process according to claim 1, wherein the image-recording material is in roll configuration. 9. The image-recording process according to claim 1, wherein the image-recording material is selected from any one of an electrophotographic material, a heat-sensitive material, a sublimation-transfer material, a heat-transfer material, a silver halide photograph material, and an ink-jet recording material. 10. The image-recording process according to claim 9, wherein the image-recording material is the electrophotographic material comprising a support, and at least a toner image-receiving layer and a toner disposed on the support. 11.
