A developing system for latent images wherein a rotating fur brush receives marking particles from a donor assembly comprising a plurality of discrete elongated donor members which are successively moved through a closed path defining a volume within a sump housing, a portion of the defined volume being occupied by marking particles contained in the housing. The donor members may be circular, crescentic, or other configurational cross-sections and may or may not cooperate with a doctor blade. They may be in the form of taut flexible elements which are vibrated slightly to remove excessive toner. In certain embodiments, a striking element in the form of a thin taut but flexible wire or other material is used to charge and fluff the fibrous applicator as well as redistribute undesirable concentrations of toner within the applicator.
