Abstract
An image forming method comprises the steps of applying a laser light imagewise and sequentially onto a laminate for image formation and separating the image receiving sheet from other materials of the laminate so as to keep on the image receiving sheet an imagewise transferred image formation layer comprising the thermoplastic resin and pigment. The laminate for image formation comprises, an image transfer sheet comprising, in order, a support sheet, a light-heat conversion layer containing a light-heat conversion material which absorbs a laser light and instantly produces a heat, a heat sensitive releasing layer containing a material which produces a gas upon receiving the heat produced in the light-heat conversion layer, and an image formation layer which comprises a thermoplastic resin and a pigment, and an image receiving sheet via a thermally fusible material in the form of a large number of dots or in the form of lines to divide an interface between the image formation layer and the image receiving sheet into different areas. The material of the heat sensitive releasing layer can be incorporated into the light-heat conversion layer.
