Abstract:
1. A multicolor image-forming membrane heat transfer system comprising: an image-receiving sheet comprising an image-receiving layer; and at least four thermal transfer sheets each comprising a support, a photothermal converting layer and an image-forming layer, and each having a different color, wherein an image is formed by the method comprising the steps of: superposing each one of the at least four thermal transfer sheets on the image-receiving sheet to be in a state of the image-forming layer being in contact with the image-receiving layer; and irradiating the thermal transfer sheet with a laser beam to membrane heat transfer an image in an area of the image-forming layer subjected to irradiation onto the image-receiving layer, wherein the transferred image has resolution of 2,400 dpi or more and an area of the image-receiving layer on which an image is transferred is a size of 515×728 mm or more, and the surface of the image-forming layer has a smooster value of from 2.3 to 50 mmHg, a ratio of the reflection optical density (OD
