    摘要： The present invention relates to a toner and process for making the improved toner. The improved toner comprises a toner resin comprising: at least one colorant; (b) at least one toner resin mixed with the colorant and formed into combined colorant and resin particles having an average size less than 15 microns; and (c) surface additive particles wherein the surface additives are adhered to the colorant and toner resin by an impaction process in a quantity greater than three (3) percent of the combined weight of resin and colorant in the toner. The invention also relates to an improved process for making toners, comprising: (a) forming toner particles averaging 4 to 10 microns in size and comprised of at least one toner resin and at least one colorant; and (b) blending sufficient surface additive particles and the toner particles in a high intensity blender for less than 10 minutes such that the weight of surface additives that become attached to toner particles is greater than three (3) percent of the weight of the classified particles

    摘要： 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.
