Abstract
An electrophotographic method comprises developing an electric latent image formed on a photosensitive member comprising a photoconductive material and containing a first color forming agent in a surface for forming a visible image with a charged toner particle containing a second color forming agent, and heating to cause a thermal color forming reaction therebetween resulting in formation of a colored fixed image on the photosensitive member.

A toner image receiving sheet for producing a low-temperature, heat fixed color image from a colorless or light colored toner image containing a color forming agent (A), said receiving sheet consisting essentially of:
- a color forming agent (B) selected from the group consisting of diarylphthalides. leuco auramines, acryl auramines, .alpha.,.beta.-unsaturated arylketones, basic monoazo dyestuff, rhodamine B lactone, polyaryl carbinols, benzoindolino spiropyrans, phthalans and spirophthalans;
- a material having a melting point ranging from 40.degree.- 130.degree. C selected from the group consisting of fatty acid, fatty acid metal salt, fatty acid esters, fatty acid amide, fatty acid anilide and solid plasticizer;
- and
- a paper sheet or web support associated with said color forming agent (B) and said material having a melting point ranging from 40.degree.- 130.degree. C;
- wherein said receiving sheet contains between 25 - 130 parts of said material having a melting point ranging from 40.degree.- 130.degree. C per 50 parts of said coloring forming agent;
- and
- wherein said color forming agent (B) is adapted to react with said color forming agent (A) in said toner image upon heating to produce said low-temperature, heat-fixed colored image.
