Toner compositions

摘要

Single component toners are provided with at least one surface additive including a large polymeric spacer, and processes for producing the same. In embodiments, the toner is a nonmagnetic single component toner produced by emulsion aggregation methods. The large polymeric spacer additives provide excellent flow characteristics to the resulting toners, and reduce the incidence of clogging failure and print defects such as ghosting, white bands, and low toner density compared with conventionally produced toners.
