An image supporting member that fixable supports a color toner image has a base material, a light scattering layer formed on the base material and containing a white pigment and a thermoplastic resin, and a color toner receiving layer formed on the light scattering layer and containing at least a thermoplastic resin, wherein the thermoplastic resin of the light scattering layer is made of a polyolefin or a polyolefin copolymer, a temperature T at which the viscosity becomes 5.times.10.sup.3 Pas being 120.degree. C. or higher, and the thermoplastic resin of the color toner receiving layer is a polyolefin copolymer, a temperature t at which the viscosity becomes 10.sup.3 Pas being from 90 to 120.degree. C. Further, an image forming apparatus using this image supporting member is also provided.
