Abstract

A composition for developing electrostatic latent images in electrographic printing or copying machinery is provided in which 10% to less than 40% by weight of a carrier having a mean particle diameter of from 10 to 35 mu m is blended with a magnetic toner comprising magnetic powder and a resin. Conventional charge control agents, especially metal complexes of azo dyes and Nigrosine dyes should be excluded from the magnetic toner.
