摘要： 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/µm with a variation during development of from 0 to 0.25 fC/µm and the distribution is substantially unimodal and possesses a peak width of less than 0.5 fC/µm, and the toner has a triboelectric charge of from -25 to -70 µC/g with a variation during development of from 0 to 15 µC/g following triboelectric contact with carrier particles. The toner has an average particle diameter of from 6.9 to 7.9 microns and a size distribution such that 30% or less of the total number of toner particles have a size less than 5 microns, most preferably 15% or less, and 0.7% or less of a total volume of toner particles have a size greater than 12.70 microns. 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.
