Abstract (en)

[origin: WO0217313A1] The invention relates to a universal carrier for a two-component developer comprising a carrier base component and a carrier pre-ageing component having at least one portion of toner resin and/or at least one surface additive. Said carrier base component is in the form of at least partially equalised particles. One part of the carrier pre-ageing component adheres to the outer surfaces of the particles of the carrier base component, and another part of the carrier pre-ageing component is contained in surface cavities pertaining to the particles of the carrier base component. Compositions consisting of the inventive universal carrier and standard toners produce a two-component developer which requires no toner-specific pre-ageing, and can be directly used in the printer.
