ABSTRACT:
Disclosed is an apparatus for heat development of a migration imaging member containing migration marking material and a softenable material capable of softening upon exposure to heat at a development temperature, which apparatus comprises a heating source, a conveyance means for conveying the migration imaging member past the heating source, a first pinch roller in contact with the conveyance means, and a second pinch roller in contact with the conveyance means, wherein the imaging member passes through a nip between the conveyance means and the first pinch roller subsequent to entering the apparatus and prior to exposure to the heating source and passes through a nip between the conveyance means and the second pinch roller subsequent to exposure to the heating source and prior to exiting the apparatus, wherein the surface temperature of the first pinch roller is maintained at a temperature at least 20.degree. C. below the development temperature of the migration imaging member during the period in which the first pinch roller contacts the migration imaging member, wherein the surface temperature of the second pinch roller is maintained at a temperature at least 20.degree. C. below the development temperature of the migration imaging member during the period in which the second pinch roller contacts the migration imaging member, and wherein the heating source is maintained at the development temperature of the migration imaging member during development.
