1. An image forming device comprising: a rotating drum having a peripheral surface around which an image forming material is trained, ink receiving portions and ink non-receiving portions being formed on said image forming material by at least one of exposure of a color separated original by active light and developing processing effected after said exposure, said ink receiving portions and said ink non-receiving portions corresponding to said color separated original; an ink sheet conveying mechanism which conveys an ink sheet, said ink sheet comprising a supporting body having ink provided on a surface of said body, synchronously with rotation of said rotating drum; ink transfer means for fitting together said image forming material, said image forming material being trained around said rotating drum, and said ink sheet, said ink sheet being conveyed by said ink sheet conveying mechanism, and transferring ink from said ink sheet to said ink receiving portions of said image forming material and said ink sheet in a state in which said image forming material and said ink sheet are fit together; and conveying means, having an image receiving material loading surface, for reciprocally moving an image receiving material provided on the loading surface in a direction tangent to the peripheral surface of said rotating drum synchronously with the rotation of said rotating drum, and fitting together said image receiving material with said image forming material to which the ink has been transferred by said ink transfer means, and for applying at least one of a predetermined pressure and a predetermined temperature to said image receiving material and said image forming material so that the ink is transferred from said image forming material to said image receiving material.
