摘要:
A process for preparing toner compositions using a dry pigment is provided. The process comprises combining a base toner resin composition, a dry pigment, and dispersion agent in a one step process, without the need any pre-processing of the pigments such as by, for example, flushing. The process includes combining the base toner resin, dry pigment and dispersion agent in a processing apparatus such as an extruder. The process may also comprise preparing the toners via an extrusion process utilizing a screw having a configuration designated herein as a Type C screw.
