Abstract

Loose toner particles carried by a flexible support are fused thereto by cylindrically curling the support about the longitudinal axis of a flashlamp, and momentarily energizing the flashlamp while the toner-bearing support is curled thereabout. A transport mechanism, adapted for use in a high-speed recording apparatus, advances a toner-bearing sheet along a circular path such that the toner-bearing surface of the sheet is untouched and continuously faces toward the center of curvature of the path.
