Abstract: The present disclosure describes a black single component toner with desirable fusing performance.

Abstract: The present disclosure provides toners and methods for their production. In embodiments, the amount of coagulant utilized in producing those toners may be less than amounts currently in use, which may have a beneficial effect by reducing the time for coalescence. Modified waxes may also be utilized which provide excellent gloss and charging characteristics.

Abstract: The present disclosure describes a black single component toner with desirable fusing performance.

Abstract: Use of a resin blend of a petroleum based resin and a bio-derived polyester resins having low glass transition (Tg) values in a toner composition is disclosed. The resulting novel bio-based toner exhibits desirable characteristics such as good blocking performance and excellent fusing latitude.

Abstract: The continuous process for manufacturing toners disclosed herein includes continuously feeding components of a toner composition into a feed section of a screw extruder at a controlled rate. The continuous process for manufacturing toners may include feeding the components of a toner composition into the feed section of a screw extruder without performing an external or secondary dispersion step. That is to say, the components of the toner composition may be fed directly into the extruder without using dispersions of individual components as used in batch processes. Rather, the toner components are added to the extruder in dry form, melt-mixed, and may be dispersed in aqueous form in the extruder. The process may produce micron-sized toner particles, thus no further size reduction may be necessary.
