Abstract
Abstract By means of a toner powder comprising crystalline polyester resin having a melting point between 50 and 100°C, a powder image is formed on a medium whose surface consists of a material having a lower affinity forthe softened toner powder than an image receiving material. The powder image is transferred to the image receiving material by pressing the image receiving material against the image bearing medium. Before and/or during the pressure contact between the medium and the image receiving material, the powder image is softened by heat.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
102 words
A process for forming fixed images on image receiving material, in which by means of toner powder comprising thermoplastic resin, an image is applied to a medium whose surface consists of material having a lower affinity for the softened toner powder than the image receiving material, and the toner powder is transferred by pressure to the image receiving material, the toner powder being softened by heat before and/or during passage through the pressure zone, characterised in that the image is applied by means of toner powder comprising as thermoplastic resin crystalline polyester having a melting point between 50 and 100 0 C.
Claim 2
Dependent Claim
102 words
A process for forming fixed images on image receiving material, in which by means of toner powder comprising thermoplastic resin, an image is applied to a medium whose surface consists of material having a lower affinity for the softened toner powder than the image receiving material, and the toner powder is transferred by pressure to the image receiving material, the toner powder being softened by heat before and/or during passage through the pressure zone, characterised in that the image is applied by means of toner powder comprising as thermoplastic resin crystalline polyester having a melting point between 50 and 100 0 C.
Claim 3
Dependent Claim
29 words
A process according to claim 1, characterised in that the image is formed with toner powder comprising crystalline polyester having a melting point between 60 and 85 0 C.
Claim 4
Dependent Claim
28 words
A process according to claim 1, characterised in that the image is applied with toner powder comprising crystalline polyester having a number-average molecular weight of at least 5,000.
Claim 5
Dependent Claim
28 words
A process according to claim 2, characterised in that the image is applied with toner powder comprising crystalline polyester having a number-average molecular weight between 8,000 and 45,000.
Claim 6
Dependent Claim
28 words
A process according to any of the preceding claims, characterised in that the toner image is softened by heating only the medium upon which the image is applied.
