Abstract:
A method () for forming a microtoner (C) for use in the development of electrophotographic images includes blending at least one polymer (P, P, P, . . . P) with at least one thermoplastic polymer (P, P, P, . . . P) and with one or more pigments to thereby form a dry mix toner formulation (D). The dry mix toner formulation (D) is melt mixed to thereby form a melt mix toner formulation (M) which is pulverized into an unclassified intermediate toner mix (U). At least one surface treatment addenda material (X) is dry blended with the unclassified intermediate toner mix (U) to thereby produce a surface treated unclassified toner mix (S), which is then classified to produce a surface treated classified microtoner formulation (C) having an improved particle size distribution.
