ABSTRACT:
Small amounts of a latent solvent are added during the initial powder impaction of the powder coating process of toner carrier particles so as to avoid excessive heating. The temperature of the mixture is raised until the solvent softens the polymer, thereby making the coating uniform. Solvent is later removed to obtain the dry coated carrier. The process is especially useful when using coating materials which have a thermal processing narrow temperature range.
