ABSTRACT:
A method of forming an electrophotographic color transfer image comprising forming at least one color toner image on a transfer layer provided on the surface of an electrophotographic light-sensitive element by an electrophotographic process and heat-transferring the toner image together with the transfer layer onto a receiving material wherein the surface of the electrophotographic light-sensitive element has an adhesive strength of not more than 200 gram.force, which is measured according to JIS Z 0237-1980 "Testing methods of pressure sensitive adhesive tapes and sheets" and the transfer layer mainly contains a thermoplastic resin (AH) having a glass transition point of not more than 140.degree. C. or a softening point of not more than 180.degree. C. and a thermoplastic resin (AL) having a glass transition point of not more than 45.degree. C. or a softening point of not more than 60.degree. C. in which a difference in the glass transition point or softening point between the resin (AH) and the resin (AL) is at least 2.degree. C.
The method is excellent in obtaining color duplicates having good image quality without color shear and good storage stability at a low cost. An electrophotographic light-sensitive material suitable for use in the method is also described.
