Abstract
A color toner composition includes dyed toner resin particles having a volume average diameter in the range of from about 2 microns to about 10 microns with a size distribution span value of less than 1.0. Preferred particles are characterized further by a micro-serrated surface exhibiting a roughness index value larger than about 1.2. The resin toner particles are prepared utilizing a dye-mediating co-solvent which facilitates transfer from a dispersion medium to the resin particles.
