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/&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.
