PURPOSE:To obtain a superior image efficiently by one time exposure and one time development unaffected by the atmospheric humidity, by providing a color forming layer containing an active clay and having a specified surface resistivity on a paper base and on this layer a specified dielectric layer capable of infiltrating colorless sublimable dye molecules through itself. CONSTITUTION:Color forming layer 3 contaning an active clay 2 and having surface resistivity <=10<9>OMEGA irrespective of the atmospheric humidity is formed on paper base 1. Dielectric layer 4 containing 10pts.wt. mixture of polyethylene PE and a styrene-butadiene copolymer SB at a PE/SB wt. ratio of 1:(0.3-1), and 25- 70pts.wt. is laminated on layer 3 to form an image receptor. A sharp transferred fogfree image is obtained on this image receptor by forming a particle image containing colorless sublimable dye particles on a photoreceptor by one time exposure and one time development, overlaying layer 4 on said particle image, and transferring the image electrostatically. |
