Abstract:
A method of fire fixing an image on a heat-resistant solid surface comprising the steps of:attaching closely to a heat-resistant solid surface, a toner image bearing film member comprising a resin film which bears thereon a toner image which is formed, using a solid developer comprising a carrier and a toner which comprises a thermoplastic resin and a coloring agent having a chromatic color and capable of retaining said chromatic color even after said toner is sintered, in such a direction that when said thermoplastic resin of said toner image has a higher sintering temperature than that of said resin film, said toner image comes into contact with said heat-resistant solid surface, while when said resin film has a higher sintering temperature than that of said thermoplastic resin of said toner image, said resin film comes into contact with said heat-resistant solid surface, and sintering said toner image bearing film member so as to fix said toner image to said heat-resistant solid surface at a temperature at least as high as the higher of the sintering temperature of the resin film and the sintering temperature of the thermoplastic resin.
