Abstract: A low energy consumption monochrome particle includes a core latex having a core a glass transition temperature and a weight average molecular weight. A shell encapsulates the core and includes a shell latex having a shell glass transition temperature and a weight average molecular weight. The glass transition temperature of the shell latex is higher than the glass transition temperature of the core latex. The weight average molecular weight of the shell latex is lower or higher than the weight average molecular weight of the core latex. The low energy consumption monochrome particles are suitable for high speed printing in SCD systems while decreasing minimum fusing temperature, maintaining excellent hot offset and storage, and exhibiting a matte finish.

Abstract: Bio-based toner compositions that exhibit excellent performance and provide high print quality. More specifically, the present bio-based toner compositions comprise greater than 20% bio-resins but avoid the moisture sensitivity issues that bio-resins are prone to by also including one or more oil additives.

Abstract: A toner for particular use in devices utilizing hybrid scavengeless development includes toner particles of at least one binder, at least one colorant, and optionally one or more additives, the toner exhibiting a charge per particle diameter (Q/D) of from −0.1 to −1.0 fC/&mgr;m with a variation during development of from 0 to 0.25 fC/&mgr;m and the distribution is substantially unimodal and possesses a peak width of less than 0.5 fC/&mgr;m, and the toner has a triboelectric charge of from −25 to −70 &mgr;C/g with a variation during development of from 0 to 15 &mgr;C/g following triboelectric contact with carrier particles. Use of a toner with such properties in a hybrid scavengeless development apparatus enables images to be achieved with properties similar to that achieved in offset lithography.

Abstract: A method of forming a toner having controlled properties for use in a developer composition finding particular use in a hybrid scavengeless development scheme includes feeding at least one binder and at least one colorant into a mixing device at a feed ratio, upon exit of the mixture from the mixing device, monitoring one or more properties of the mixture with at least one monitoring device, wherein if the monitoring indicates that the one or more properties being monitored is out of specification, removing the monitored mixture from the method and adjusting the feed ratio by adjusting the feeding of the at least one binder or of the at least one colorant, thereby retaining in-specification mixture in the method. The in-specification toner is ground, optionally together with a portion of one or more external additives, classified, and mixed with one or more external additives to obtain the toner having controlled properties.
