    • Disclosed is a process for depositing marking material onto a substrate which includes (a) providing a propellant to a head structure, said head structure having at least one channel therein, said channel having an exit orifice with a width no larger than about 250 microns through which the propellant can flow, said propellant flowing through the channel to form thereby a propellant stream having kinetic energy, said channel directing the propellant stream toward the substrate, and (b) controllably introducing a particulate marking material into the propellant stream in the channel, wherein the kinetic energy of the propellant particle stream causes the particulate marking material to impact the substrate, and wherein the particulate marking material comprises toner particles which comprise a polyester resin, an optional colorant, and poly(3,4-ethylenedioxythiophene), said toner particles having an average particle diameter of no more than about 10 microns and a particle size distribution of GSD equal to no more than about 1.25, wherein said toner particles are prepared by an emulsion aggregation process, said toner particles having an average bulk conductivity of at least about 10−11 Siemens per centimeter.
    • 公开了一种用于将标记材料沉积到基底上的方法,其包括(a)向头部结构提供推进剂,所述头部结构在其中具有至少一个通道,所述通道具有宽度不大于约250微米的出口孔,通过 所述推进剂可以流动,所述推进剂流过通道从而形成具有动能的推进剂流,所述通道将推进剂流引向基底,和(b)可控地将颗粒状标记材料引入通道中的推进剂流中, 其中推进剂颗粒流的动能导致颗粒状标记材料冲击基材,并且其中颗粒标记材料包括包含聚酯树脂,任选着色剂和聚(3,4-亚乙基二氧噻吩)的调色剂颗粒,所述调色剂 颗粒的平均粒径不大于约10微米,粒径分布 GSD的离子等于不超过约1.25,其中所述调色剂颗粒通过乳液聚集方法制备,所述调色剂颗粒的平均体积电导率为至少约10-11西门子/厘米。
